The Stovebolt Site Forums The Parking Lot Big Bolts Source(s) for 5.43 gearset 2352908??

Have you tried a search on GM H110 axle. GM built that axle for about 25 years. I think 1968 was about the last year. Are you trying to re ratio? Owners of 1 1/2 ton GM trucks have been trying to make them go faster for over 50 years and the 5.43 are probably getting scarce.
