Coming down to the end of my rebuild and seem to have misplaced dome of the bolts......been doing quite well until now.
Right now missing the 6 bolts holding the flywheel to the crank and the 3 holding the coupler to the flywheel; are there 3 "triangular" washesr for the coupler? Can these washers be replaced w/ round ones?

buy new flywheel bolts for the flywheel. I suggest ARP or Manley

buy new grade 8 bolts for the coupler. should be 3/8-16 about 1" long. the triangular washers were developed to spread the area out to prevent cracking. while you can use regular grade 8 hardened washers, I would suggest the correct "triangular" washers.

coupler bolts are called "shoulder bolts" ,not your standard bolt
