GM Parts Store is still showing the standard PF64 (part #12706595) for our cars (LT1 engines): https://www.gmpartsstore.com/oem-par...YtMmwtdjgtZ2Fz |
Appreciate your input here. Yesterday, my dealer sold me both the PF64 and UPF64R. I bought both with the plan of coming back home and going thru the forums to see if the "R" was recommended. I installed the original.
