Have some new GM parts left over:
GM 3894337 Valve Cover Grommet - $5 each incl shipping (I have 1 left)
GM 3798372 Windshield Wiper Bottle Cap - $6 each incl shipping (I have 1 left)
GM 3927019 Sway Bar Bushing set (2) - $10 incl shipping
Valve cover grommet fits on I6 PVC. Can be used as plug or grommet. May fit other engines also.
Sway bar bushings are for 1" bar.
If interested in several items, let me know and I'll knock off a few bucks to combine shipping. Planning to ship USPS parcel post. If you want them sooner, can ship Priority. $5 Priority for small items, not sure about sway bar bushings as they are bigger.
Thanks.
