trans mount

What are you using for trans mount car has mid plate and front plate but the trans is mounted solid to cross member what's your thoughts on this 904 trans and if you are using a mount what make or kind I would just have to change cross member and car is going to to shop soon for some up dates they could do while it's there. THANKS

My last S/P 1970 Cuda (chromoly tube chassis car) had all three, front motor plate, rear motor plate and a tranny mount with a removal tranny tunnel. That was good
It was the easiest car I've owned to remove the tranny and converter

Poly.

Periods are friends.

poly certainly wouldn't hurt.
a common GM mount can be easily modified to fit, basically just slotting the mounting holes and a slight shave off the outer edges of the poly itself.
plus, the GM mount is shorter than the mopar mount, allowing the crossmember to be fabricated easier.
