i got a b18a1 and just bought a obd1 dist. from somebody on here and when i got it the bolt holes did not line up is there a difference in obd1 dist. or what would cause that to happen?

 

which OBD1 distributor did u buy? the B18 non vtec dizzy should have a bolt pattern that looks like a triangle. if any of the ears are slightly off u might have a vtec dizzy or possibly a sohc dizzy. pics would help. i have a bunch of b18 dizzy for sale. PM me for that i dont wanna turn this to a F/S add.
