The plastic peice that goes in the groove on the opti (the part that goes into the hole) broke when I was trying to put it in, can i just buy a replacement peice? Also what is this peice called? If u guys need pics i can post em. The motor is a 94 roadmaster motor.

Is it the piece that's similar to key stock?
Pics would help.

there was a little plastic ring right there and it shattered off when my friend was trying to put the opti on. is there suppose to be 2 of those rings (one on each groove) or just one?

If it's just a plastic ring. Take the dowel pin to a hardware store and find a replacement. I believe there's just 1. I could be wrong.

The grooves are for rubber O rings [2 of GM p/n 10474278 ] that have ossified and hardened and appear to be plastic..
