If you use a 4l60 you likely won’t have to do that and it will bolt right in. Also be sure the pan will fit. I used a Holley swap pan and it fits fine. The Tilden comes with motor mounts included along with bolts. The other thing I like about it is you don’t have to move your brake lines.
Thanks for the info on the crossmember. I am using a 4l60e. If I can figure out how to get pictures on the site I will show my progress. I have rust free 72 all stock. It should be a good build.
