Are all the gears used in the C4 pump the same….as in interchangeable? I have an early C4 pump (67-69) that has a cracked gear. PO apparently didn’t have TC seated properly and probably forced it together with bell housing bolts, cracking the gear. I have a few “ parts transmissions“ that I may be able to rob some gears, but wasn’t sure if they were the same. I only see 1 set of gears on summit, and it doesn’t specify specific years, so it leads me to believe they are the one in the same. And those “Hughes performance” gears can be drop shipped in March of 2022. Can someone with more knowledge verify my thoughts? Its pouring rain so I haven’t gone into the shop to start comparing parts….
