What size is this bolt?
 

Just what bolt are you asking about ??:coffee:
M8x1.25 most likely

7:29. These are 8mm bolts. And either 8x1.25 or 8x1.5. Just find a bolt with a 12mm head in ur engine bay somewhere and use that...inlet manifold bolt, quarter panel bolt, radiator mount bolt...something like that

Toyota use all 1.25 thread pitch in the 8MM 10mm and 12mm bolts:coffee:

Never thought of that, great tip!
