2023 Driveline Rebuild (Rear End)
A Rear Spring Liner Set was purchased for use during the rebuild. Steve from SR took the spring out to K-MAC Suspension to have it fitted, but Kevin Mcintyre (the founder of K-MAC) said this part was rubbish and that the original liners were better quality, so we kept the factory liners.
The diff housing in the Red Rocket has casting number #3818753-N. Diff housings in 1965 used casting #3818753-N until February, replaced by #3876476N which carried through 1966 (the "N" means nodular iron, vs. grey iron). The code 'AP' stamped on the diff housing indicates a 4.11:1 (refer to Corvette Rear Axle Codes & Ratios link below). The diff housing date code is 1-14-65 (14 January 1965), which, together with the casting number, confirms that the housing is original to the car.
