Dave,
The part on the frame where the trunnion bracket attaches should be threaded on
the inside (facing the radiator). You should be able to see the nuts welded to
the frame attachment. I am not sure what the thread size is but 3/8 sounds
about right. I believe it is a NF thread size. If your frame is not threaded,
the DPO must have drilled them out. I think it would be best to cut the old
nuts off and replace with a spot weld or braze.
