The main bearing caps? The A12 factory bolts are super-strong and are the same ones as used in L18, L28, Z24 and KA24E. So you can use ARP 202-5401a main bolt kit or Kameari Engine Works 202-5401A, but there's no need as the stock bolts do not fail in an A12

DD...same thing for A15 bolts? No need to look for replacements? Plan to torque down the crankshaft soon. Also is it necessary to use locktite?

Yes all A-series use the same main bearing cap bolts: A12, A14 and A15. Locktite is not recommended

don't forget the main bolts are 37 years old when you put out good hp you need something a bit stronger. I haven't had any problems so far, but this new combo I'm doing trying to keep it safe
