I used the the same Comp. Eng. plate, .090 thick. I used their spacer that came with the kit. I did not cut it out for the starter. Starter engagement is fine. Works just fine. However the problem I had was the spacer plate now made my flex plate bolts to short. It did not have enough thread engagement to the crank flange. Mopar does not make a longer bolt. I used Pontiac convert bolts and ground down the heads to make slim headed bolts like the Mopar's. Worked out just fine. The bad thing is I had to buy two packs of bolts because the Pontiac flex plate uses less bolts.
