Yep 70rs/ss, you are right. Fastom does have the narrower frame. Good eye! I can't believe I didn't see that! Oh wait, yes I can! LOL
Anyway, not sure about the mounts, anything is possible since the PO installed the engine. He did some interesting things on this truck....
DS mount:
PS mount:
And the headers hit in these locations:
You can see where I could tuck the rear part of the headers in a bit more to get frame clearance, but they would just hit the engine mount even more...
