Ever order parts from "Autoatlanta.com"...?

Old Man Powell · March 20, 2014, 09:43 AM

I was just doing some browsing again and the website www.autoatlanta.com came up for brake parts for my 1974 RM400 chasis. Sure enough they have quite a few items, including rotors and even drums (however they are for the 8 lug wheels). Anywho, has anyone ever ordered from them? Proces are very reasonable from what I can tell.

looks like the parts are correct for the m400 chassis dual piston calipers, 8 stud wheel just ordered front brake pads and new wheel cyclinders for the rear brakes we will see what there like let you know when they get here in Canada

Old Man Powell · March 20, 2014, 10:07 AM

My biggest concern was the 8 lug items were listed for the RM400 which is 5 lug. Maybe it's just a "stock photo." Wonder if the calipers for the M400 and RM400 are the same. Just hate to order parts (calipers) and have them be the wrong ones. I emailed them... see if they reply.

joev · March 20, 2014, 10:25 AM

got a email confirming my order already so we will see

Old Man Powell · March 20, 2014, 10:28 AM

Nice... keep me posted and good luck! Do you have one or two wheel cylinders per rear brake? Just curious... I have two (four total)

joev · March 20, 2014, 10:30 AM

Getting the correct brake parts here in ONTARIO is not so easy for the front brakes and costs are more that double the cost from them

joev · March 20, 2014, 10:33 AM

nope just one on each side two in total mine is a m400 8 stud
RM400 is the 5 bolt pattern I believe

I am doomed to always keep telling everyone:

the 74-75 Dodge Motorhome Service manual supplement states that for 73-75 (YES I SAID 73 - 75; the RMxxx designation started in 73)

RM300 is redesignated to M300

RM350 is redesignated to M400, and

RM400 is redesignated to M500

If you go look for M500 parts (typically considered a Medium Duty Truck) you will find your RM400 stuff

Now the confusing part is that due to when Dodge made this redesignation, many of the M400 aftermarket parts were already listed under RM350 not M400 (especially brake disks hint hint). So for M400 (RM350) you have to look ------> both ways <--------

Dave

PS: Yes,
M500 (RM400) is a 5 bolt, 19.5" rim and
M300 (RM300) / M400 (RM350) is a 8 bolt 17.5" rim
Pre-73 M375 used 5 bolt 17" split rims
Early M300 used 8 bolt 16" split rims
Don't remember specs for the rest of the top of me head.
Also, M300 (RM300) uses single piston front brake calipers and the M400 (RM350) / M500 (RM400) uses dual piston front brake calipers.

Thanks Dave for clearing that up Trying to buy brake parts here in Ottawa area nightmare nobody stocks the parts and they all look at you like your from outer space even when you give the part #s they still cant find them

joev · March 20, 2014, 09:30 PM

I believe this is what your looking for

check the specs you have to look under M500 1978

DaveVA78Chieftain · March 20, 2014, 10:16 PM

Old Man Powell,
You rear brakes are like this:
Bendix Twinplex Brake Systems

My question though is what exactly are you looking for?
Dave

Old Man Powell · March 21, 2014, 09:08 AM

I was just browsing different options for brake parts. I noticed "their" info for the RM400 chassis did not match what was reality. They show a RM400 and M500 chassis as needing only one wheel cylinder per rear assembly. Also, the info showed an 8 lug rotor and drum for the RM400/M500 which I thought only came with the 5 lug. That's all. Wasn't trying to add to the confusion or anything. They might be a good source for parts but I have some hesitation as to the "accuracy" of their knowledge of these chassis.

joev · March 21, 2014, 09:26 AM

That's what i have been running into here nobody knows whats what, you have to do some digging to find what you want, and check the specs on all parts just to find out your cant get them here lol seems like available in USA but not here tried to get brake rotors here and they wanted almost $300 each special order no guarantee there the right ones you order and there yours.

DaveVA78Chieftain · April 16, 2014, 05:48 PM

Just curious. Did you use the information I provided or something else. Future readers will want to know.

Happy to hear it's coming together for you,
Dave

joev · April 16, 2014, 06:02 PM

pvoth1111 · April 16, 2014, 08:48 PM

......Insider info...... Auto Atlanta used to be "THE" best place for Porsche 914 parts......and other Porsche parts.....( ive restored lots of Porsches) in the last few years they got into other parts.....they are a tiny physical place.....they don't stock all that stuff....most likely they teamed up with Rockauto or some other mega warehouse.....I have a website too.....and know how this stuff works....if you think they gave ya a deal good for you....rock auto is the amazon of auto parts.....start there

Stripe · April 17, 2014, 01:12 AM

I get all my Porsche parts from RenBay and Pelican Parts, Always treated me great and send cool goodies to me every now and again like Matchbox Porsches and Stickers..

Old Man Powell · April 17, 2014, 07:53 AM

Glad you got the parts and they are correct! Man, can't believe it takes so long for the parts to get to Canada. Then again, yes I can. That would drive me crazy with anticipation. Now the fun part, putting on all those new parts on! I gotta admit, once I finally tore into mine it was very, very easy. Well, the front was, didn't have to do the rear brakes... yet. Just be sure to check the wheel studs on the driver side of the rig. I'm are left handed. PO painted over the L on the studs... long story! Just don't be an idiot like me! It's little things like that that make these projects so interesting... but can also turn a quick repair into a frustrating knuckle bleeder!

Dave... I personally used all the info you provided. Huge, huge help! Can't thank you enough.

Finally took the time to see what you ordered. You confused me at first as I thought you using the information in the M500 post for Old Man Powell above. I see you actually have a M400 chassis which now makes your numbers make sense. Glad you worked it all out.

Old Man Powell - Your welcome

joev · April 17, 2014, 03:42 PM

some stuff you can get at the local Napa store no problem other stuff looks like you can only get it in the U S i?? i?? and then you have to wait on it Hm? Hm? and wait Hm? and wait Hm?

DaveVA78Chieftain · April 17, 2014, 07:51 PM

Maybe TJ has some ideas on reducing the wait.

Although I live very close to the border and can get to the NAPA in the US almost as fast as the one here, I have learned that you go on the NAPA online site (US, not Canada) and get their part number for a particular part that the Canadian supplier (even NAPA) tells you they don't have a listing for. Once you have a part number, they seem to be able to locate the part easily. Some of the parts suppliers in Canada don't even have listings that far back anymore. Rick
