Just looking for some replacement nut & bolts for missing ones (unfortunately I need a new tap & die set - this is easy when it's imperial).

1988 4runner w/ 22RE

Need to know what size/thread the nuts on the exhaust manifold studs are (flange to exhaust)?

Grade / length / tpi for bolts on the factory roll bar?

Thanks in advance,

Andy

 

Toyota uses JIC
so TYPICALLY its
8mm x1.25
10mmx1.25

My GUESS is the exhaust mani studs are 10mmx1.25...
(I have spare ones around so I dont bother to know anymore...)

 

On the rollbar they are 7/16 - 20 as those are seat belt bolts

Holding down the rollbar are M10 x 1.25mm IIRC and they go through the floor so the length is not crucial
