Do the old shocks have a number on them? Are they the original shocks?
The part number for a 1962 C30 and GMC 2500 and 3000 is 5549599. It Interchanges with Monroe 66878 . Summit racing list 66878 for a 1962 C50 or GMC 3500. It has an extended length of 23.906 in. They also list 66902 for a 1962 GMC 3000, the 2500 1Ton used the same shock, and it has an extended length of 23.875 in. The 66902 has L1 L1 5/8 “ ends. The 66878 has LS54 LS54 ¾ ends. EBay has a listing for a 60-62 C20 ¾ Ton (5552230) shock that has an extended length of 25-3/8". The 66660 shock is only 19.21” extended length. The Gabriel 82035 are the front shocks.
I think you need a shock longer than 21”.
