86 3500 A/C question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Swapping from a 6.2 to a 402 BB. Truck has A/C now with the small pump. Are any of the brackets usable off the 6.2 or am I going to have to source all new ones?

All new. 6.2's use nothing from the other Chevy's. Fortunately 454's with serpentine drives are not rare.
