Re: Tire pressure sensors
They appear to be NLA at Corvette Central. I believe they were GM part # 10180847 for the 91 to 96 MY.
Try this website:
http://oemcats.com/oem-parts/10180847.html
They are pricey.

Re: Bilstein FX3 Shocks
My understanding is that Bilstein considers shocks with a Delco label to be a GM part and there are trademark issues with GM. There are other rebuilders which will rebuild them with a long lead...
