Anyone know the correct color for the Air Shock Shields? Also what are the correct bolts for them? Thanks

The air shock shields are semi gloss and the bolts if I remember are 1/4" x 20 If this is not correct I will look a my one owner Tlr. Queen and get it right. All 68-72 El Caminos came with factory air shocks. The shocks are called G.M. Superlift The factory numbers for shocks are 3197337 and 3917338. My one owner 70 SS 454 M-22 El Camino has all the correct parts on it. If I can help in any way let me know. I have a set of date coded 71 Superlifts. Most of the old air shocks will leak around the rubber bags, Spray them with soapy water and what you will see looks like beer foam. Good luck!! Bob ACES--AACA
