67 C10 Frame / Crossmember Mouting Issue

I recently blasted the frame and put in epoxy. While having the frame upside down, I noticed someone had enlarged two of the crossmember holes on the driver side of the frame. Not sure why they did this, and the original bolts that came out are way too small.

What do you guys recommend? Appreciate any ideas.

1. Leave it as is?
2. Weld the holes back to original size?
3. Enlarge all the holes on the frame and crossmember to the same diameter? and use larger bolts.

I've attached an image from Microsoft One Drive

You just never know what has happened in the life of a truck before you get it. If it were me I'd probably just make the holes match and use larger bolts. Plenty of frame there to work with.

I would find the proper size bolt for the said larger holes and drill them larger if needed for a snug bolt fitment into the hole.

Thanks for the quick reply's.. I'm with ya, I'll just drill'em and use larger bolts. I'm thinking someone had enlarged those holes maybe to cant the front crossmember a bit for steering alignment purposes. Not really sure why.

It being to mount front crossmember. I think I would measure to make sure that the frame is straight before opening any more holes.
