no the frame side mounts are fine its the brackets on the motor that I have one that is right and the driver side that is off by a half an inch that I believe might be different. unless some one can tell me for sure that the 350 mount has been the same since the late seventies...
About the air I could probably run something from classic auto air I would assume or make my own bracket. Sectioning the frame right there is always another option but not one that I would like to do as I think I would need to take out quite a bit and I dont want the truck to act different in a head on collision. (part of the down side of working in the collision industry, always thinking of that)
What year f body parts do I need for the oil pan? or does it matter?
