Make sure your flywheel bolts are long enough to catch ALL of the crankshaft flange threads. Aluminum flywheels can have a thicker bolt flange - making the actual original bolts too short.

I always buy new ARP bolts, I do use the above plate and I always use Red Loctite on the threads.

The only thing to ponder is many of these plates are really scared up - so using hardened steel flat washers under the flywheel bolts is another way to do it. I've never seen the locating pins be loose, but Gary does have a good point on that aspect of using the full plate.
