I can confirm what you are saying Aaron. In the process of rebuilding my
TR4 I've been able to buy the vast majority of fasteners from a good
local hardware store, and I've been replacing virtually everything. Vast
majority are UNF and easy to find. I do recommend being careful about
the grade of fastener you buy, try to stick with grade 8 or at least 5
for anything holding together critical systems like suspension, brakes,
steering, drive train, etc.
