I ground off the rivets that secure the front crossmember and then drilled out the center. Smack it with a center punch and they pop out. Time consuming, but it works. I won't bore you with all of the rivet removals, so we'll fast forward.
I grabbed a couple of taper punches and got everything lined up. The lower pickup brackets are a little different from the 1940 crossmember that I am using as a donor. I'll have to modify it slightly.
I picked up some grade 8 bolts to replace the rivets. I had originally planned on using carriage style heads, but I read that the tension capability is severely reduced using a rounded head. I figure I would rather be safe, so I opted for the hex heads. It didn't take that long to repair and it will look better than a repaired crossmember.
