Most applications can use the stock flywheel or flex plate bolts, however if your bolts are at the bare minimum length of thread engagement now you will need to get bolts that are 1/8" longer.

This balance plate is designed to be used with a neutral or internal balance flywheel in order to achieve an external balance engine. You will also need to use the appropriate harmonic balancer for an external balance engine. This fits the 1986-96 one piece rear main small block Chevy engines.
