I have a 71 Maverick that has the 250. I am wishing to swap in a 5.0/AOD and I am retaining the electronics. I need a set of Frame mounts for a 302. Auto-Krafters is out of them at this time. I wonder if it would be hard to fabricate them? From the illustrations I have seen, they do not look that complicated. I am also considering a 4.6 modular. That would me more fabrication, I know. What do you guys think???
