Well, I can't find either sets, I have a 455 motor and 400 turbo trans. The 3 bolts for the flex plate and torque converter and 6 Trans to engine bolts. Please and Thank You. I'm so close to putting the 71 on the road. HOW about those Blues ! sorry couldn't resist. Paul OH, I don't do Paypal, so I hope a check or MO is ok.
Just go to the local hardware store and get grade 8 bolts for the engine to trans, you can get converter bolts through arp at summit or jegs, you local hardware might have short grade 8 for them. They dont need to be anything super special
I have a good supply of used flange headed 3/8" - 16 coarse SAE bolts some are likely from a Buick engine to bell housing. Some have faint traces of red paint on them. Cleaned and degreased. Got them from a friend who parted multiple Skylarks. PM for more info.
