C4 RPO Code Questions
Hey all,
I've been reviewing the RPO codes in my 84 CFI Z51 and I have a few questions.
I have the RPO code F51-Gas Shocks. I thought the Z51 came with Bilsteins.
Final question: I have RPO code KC4-Engine Oil Cooler. According to my GM parts manual, as well as any parts store I've ever been to, this was not available on the 84. It is completely different from the 85+ cooler in that my 84 cooler has oil lines going to the radiator from the oil filter. The 85+ coolers have coolant running to a coil above the oil filter.
