Also around the shock towers, which added approx 1/4 - 3/8" and sometimes get in the way of header tubes....... I think this was done on 73 and up with 302, but I have seen some with 250........ David
Yes, they are very similar to the 69/70 Boss 302 Mods, Opentracker Racing and other Mustang supply shops carry these reinforcement kits, it is nice that Ford did this at the factory on 73 and later with 302's........ https://opentrackerracing.com/product/shock-tower-repair-reinforcement-kit-1967-1970/ David
Engine size was not a factor. They were having issues with cracking. Everyone got them. I cut a set out of a 250 cid car and grafted them into my '71. Pictures in my build. Micah
