Wtb: s13 Header studs

like the title says Im looking for 4 studs which hold the headers in place, or if anyone knows roughly how big the studs are and the length of them, that would greatly help.

Thanx In Advanced

i think it is a #10 - 1.50 pitch about 2 inch long. i think , not sure. the size sould be in the FSM.
auto parts stores should have them. and i don’t mean crappy tire!

peace
