I rtealize it isnt too bad of a job to fabricate new crossmembers for tranny mounts.But you can buy them fairly reasonable from the parts houses,Brothers,Chevy Duty,Golden State,etc.There is also a nice motor mount setup,that fits in bretween the frame and is a very easy instalation.I cant remember which place I got mine from.It uses the standard small block motor mounts.Saves a lot of work.
