Finally get to pretend I am one of the cool kids - Holley kit swap

Yep. You can actually see it in the background of the last 2 pictures. 5/8 OD x .120 wall, might be overkill as it looks beefier than I expected when I picked it up. I haven't cut them to length yet and they need to be tacked in while it is in the car and after the inner holes are drilled in the original crossmember.
Yeah I see that rube laying there now. Your on it. Love have nice that cross member looks very impressive!!
