Are you going to add tubes inside bolt holes so when cross member bolts are tightened it doesn't crush cross member? I used 1 inch square tubing welded in when I did mine. That way I can tighten bolts good with no crushing. You want those bolts tight cause your gonna be burning tires grabbing gears.

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.
