Cummins 12mm rotor head 3.2mm camplate 4200rpm governor spring

[jeremysmith]

Hello, everyone! I'm a new member here, but I'm not new to forums. I've been searching everywhere, but I can't seem to find what I need. I'm looking to upgrade my pump, specifically for a 12mm rotor head from Cumminsgeometry dash subzero, along with a 3.2mm camplate. Additionally, I'm interested in acquiring a 4200rpm governor spring. Does anyone happen to know where I can purchase these items? I found a store in China that sells diesel parts, but I require the specific serial numbers for the parts. If anyone has this information, I would greatly appreciate it.
