What wears out on Trunions TR6 TR250

What wears out on trunions?

I'm trying to decide whether to use new trunions or the old ones on my 
TR250. It has 60K miles.

It looks like the only part that would wear is the pivot bolt hole. #92

I have three new trunions (don't ask) and the new bolt seems to fit 
snugger into the original trunions on the car than with any of the three 
new trunions.

Seems I should use the old trunions...  Yes/No?
