REVISITED:
Can i get some part #'s for the grommets and oil caps and breathers?
1) Would prefer an oil fill tube with cap, but would settle for just a cap.
2) Would prefer OE, but would consider high-quality aftermarket-----Dorman is probably ok, K+N, Trans-dapt probably better.......
So, this is for 87 and up vortec valve covers.
Thanks.
