re-attaching frame bracket question
Got my frame back from the painter, looks great. I'll post a picture if/when the sun comes out and the snow melts. 
Question: I know I need to use grade 8 bolts to re-attach all the mounts/brackets which were removed, but the rivets were an odd size. Do I use 5/16" bolts which have some play or do drill out the holes in the frame and mounts to use 3/8" bolts?

You could re rivet it. On a different vehicle I just finished replacing over 110 bolts with rivets to return to original. In my case I had to plug weld about 70% of the holes and drill before re rivoting. Back when the vehicle was restored, a po had removed the magority of the rivets in the frame probably the rivots had become loose (early roads).
Note: the rivets were either 5/16 or 3/8"

110 bolts. Luckily I don't have nearly that many!
So the rivets were either 5/16 or 3/8. An 11/32 bit fits perfect so I'm guessing they were drilled a little oversized and the rivets expand.
Since I don't have very many to replace, I'm going the bolt route.
