Title: Looking for Original Born-With Muncie M21 4-Speed - Assembly V0C05B / VIN 616410
Post by: Smartin72! on September 10, 2026, 11:42:56 AM
Hi all,Following up on my registry search, I am also looking for the original, factory-installed Muncie 4-speed transmission that belongs to my March 1969 Norwood-built Z/28. I have the original Protect-O-Plate in hand and would love to locate the matching gearbox if it survived.Here are the factory-stamped identifiers for the original unit:Vehicle VIN: 124379N616410Target Transmission Assembly Stamp: V0C05B (or possibly P9C05B)Target Partial VIN Stamp: 19N616410Specs: Muncie M21 Close-Ratio 4-Speed, assembled March 5th.Currently, my car has a factory-correct 3925660 main case installed, but it bears a slightly later Norwood partial VIN stamp (19N633336). If anyone has the transmission stamped for sequence 616410, or if you happen to own car 633336 and want to discuss a swap/trade to get both of our cars closer to numbers-matching status, please reach out!Thanks for checking your garage stashes and inventory racks!

That's too close to being a classified ad. 90% of the Camaros out there are missing some component of the drivetrain.
You could put your non-original trans on the orphan page and list what you are looking for.
Kinda similar, but the emphasis is on the orphan, not your missing trans.

This post will be deleted in a couple of days, fyi.
