crank bolt

[shawnxj]

for some reason i assumed the 242 and 258 shared the same bolt for the harmonic balancer but none of my bolts work and the crank i got didn't come with a bolt. so what size/thread is the bolt and anybody know offhand where to get 1? the local jy had 2 258's last month but i didn't see them when i went last week

ok had a thought and checked and it turns out the starter thread in the crank is screwed up....so still need to know what size/thread so i can go get a tap for it
