Im getting ready to rebuild the SM420 from my 57 Chevy 1/2 ton. I bought a kit from Novak, and they don't have the third gear synchro ring anymore. Do any of you know where I might find one?

Thank you,

Larry

Larry,

Try E-Pay. I gotten quite a few NOS parts off that auction site. Type in SM420 parts.

Another source you might try is Drivetrain.com. They have a synchro kit for the SM420, but not sure if it includes the 3rd gear synchro ring.

The 3rd. gear synchro cone that you need is on ebay right now at a bargain price.
Go to ebay & type in the search box: 591602
