Can't tell what '75 dodge chassis I have

[acenjason]

So, I am taking the plunge and becoming a member (making sure I have money on my card first) so that I can get the parts manual for my 1975 D21. But I don't know what chassis I need to read about when I get it. How can I tell what chassis I have? M300, etc. Thanks for reading.

For  a 75, the Dodge VIN plate may be located in the radiator access area, driver side firewall.

Thanks!

Hey thanks guys. I followed the instructions above and learned that I have the M300. I was taken aback to learn the chassis has a separate vin number than the coach. I finally figured it out by looking at the placerd under the drivers side window. Anyway, I have the correct parts coming
