Ordering parts, what do I tell them I have?

[cs641]

I have a 1975 Landau 28 footer on a Dodge chassis. 5 lug wheels, 440 engine. Disc front, drum rear.


I'm hoping to redo my brakes. What do I tell them I have when I order parts at the auto part store?

I would not be surprised if it is actually a 74 chassis.
5 lug (19.5" rims) with a 440 would be a M500 chassis.  Originally, it would have been designated a RM400 however Dodge changed that to M500 in 75 and back listed that for all RM400 chassis.

Thank you Dave! I did a lot of searching around for my data plate and found that it is the M500 chassis with a vin corresponding to 1975. Double checked my registration and it says 1976. Funny thing is I believe I heard the hydro-vac brakes went away in 74 so it makes a ton of sense to be a 1974 chassis. So it's a 74/75/65...LOL!

Thus why you have a "unfinished Chasis" manual, and a coach manual or should have both anyway.  Gone is on a 1986 Chevy p-30 Chasis but is a 1987 Tiffin.
