Front Crossmember Location(s)

[RabidScott]

Hi again, guys! Got a simple question for you!

I'm getting the 350 into my '57, and had one of those universal engine crossmembers. I haven't bolted or welded it in yet, and I noticed that the crank pulley was real close to the stock front crossmember.





Now, I noticed that there are two sets of holes in the stock crossmember, one set which must have held the original six-popper in place. The other set of holes appear to be in the correct place for the stock V8 mounts.

Long winded story short:
Could I cut the rivits off the crossmember, slide it back, and use the OE mounts for the V8? Were there two positions for the stock crossmember, depending on whether the truck was a six or V8?

I'm pretty sure thats the way it would have worked, I just wanted to make sure. I'm contemplating using the OG stuff...
