I read all through the the bolt archives in the FAQ and couldn't come up with the info I need. My motor is back from the rebuild shop and I can't find the motor mount bolts I removed. I was going to buy new bolts anyway but need a couple of questions answered. I'm speaking of the bolts that attach the mount to the block and bell housing. Are they the regular type flat head or are they shouldered? Do I use a flat washer and a lock washer both. This is a 1982 2F.
