58 gmc with 270, 3 speed standard is in the truck now. I'm putting a 70 Pontiac 350 and th400 in it. I'm looking for motor mount sources as well as trans cross member sources and suggestions on the simplest way to make this change.

I can get in there and fabricate what I need to do, however, if something already exists and will work well, I'd rather just go that route. Any other suggestions would be appreciated.

thanks
JD
