Hi Ramp...
Sorry,I don't know if you have another name..but yer mum had a sense of humour if Rampant Rivet is your real name,but anyway ,name or no name you are doing a great job on the truck..The 637 in the number refers to the gear ratio..the C15's had the 6.37:1 rear ends and the C15A had the 6.39:1 rear ends..diffs,if you prefer..
The first C8A,C8AX also had the 6.37:1 diffs... but changed down to 7.38:1...on replacement...
