We have a 71 RR that has no support, (bolt in)
Is there a difference between the 4 speed and auto support besides the
cushion?

Also, can someone tell me what crossmembers will work in our application, i.e.
years/bodies.

Thanks in advance....Joe

Found my answer, only difference IS in the isolator.

then you can bolt up an isolater according to the crossmember you are using ?

71 to 72 B Bodies and all e bodies use the same support. Manual and Auto are the same also. I think the 73 later B bodies are the same too but I could be wrong.

The older B bodies used a box shaped mount instead of the spool mount and the support must match the mount.

I'm a little fuzzy on it but I think some years used a different support for Auto vs manual. If so that ended with the spool mounts.

Yes MOPARX, it's the same support for both transmissions, just a different isolator.

I questioned Brewers and got the skinny from them,
thanks Brewers!
