Great-That is the pump and hub we have on the Jetfires. Yeah, both the A/C car and the non A/C car have the clutch. I am going to the D&D pulley on the Cutlass since I don’t have any of the HD cooling setup. I agree getting the short pump and pressing on the big hub shouldn’t be an issue. Concern is the old clutch which we need to go with if using the big hub. So who did your clutch and do you have significant miles on it?
