After seeing that Dan and Alan are going to put motor plates in and will have the engine mounted solid. Then will it matter if the transmission and transfer case are mounted solid or will You want to use the rubber trans. and x-fer case mounts. The reason I bring this up is Im installing a married transfer case in a 1972 frame which never had married x-fer cases so I'm having to fabricate a x-member for the trans. and a x-fer case bracket.
I'm wondering if I will have to use rubber mounts like factory or can I do solid mounts. It would be way easier to go without rubber mounts. Without the rubber it would seem like something would have to break because of the torque of the engine.

Solid motor plates, you better have a flexible transfer mount. No frame is so rigid that it won't flex/twist and potentially break trans housing or trans to transfer adapter.

Ditto!

I was actually thinking about fabricating a crossmember such that the tranny would rest on it to take the weight off the motor, but not have it bolted down. Don't know yet how that would work!

Alan

I have a rubber mount on my tranny cross member.

Dan

Are you using the stock C6 rubber mount?

Well back when I was redoing ShaZam a few years back I needed a tranny mount so I headed to Car Quest and started looking thur there Book of Motor and Tranny mounts and got this one from a 1970's something Torino with a 429 and C6. Seeing how I was making my own cross member it didn't matter what it looked like just that it had some rubber in it. It's been doing a good job ever since.

Dan:what size steel did you use to make your x-member?

I used some 1/8" 2x2 Sq. tubing .
