Probably lots of places, but I am looking at a catalog from "Hot Rod and Custom Supply" and they have a kit for $ 109.95 that are bolt in motor mounts, and for $ 32.95 you can get the tranny mount to put a 350 turbo behind it.

Their phone number is 1-800-741-4687 or www.rodncustom.com.

Man, these prices are like 1959 all over again !!!!!

Hope this helps, but I'm sure others will have more places to look.
