Ouch! | | | | | Joined: Jan 2008 Posts: 4,961 'Bolter | | 'Bolter Joined: Jan 2008 Posts: 4,961 | Do you have a 53 and earlier or 54 and later. The later ones have 4 lugs and the earlier have 2. There is a new later one on eBay for $200. If I remember correct, 2 of the lugs can be ground off. The one on eBay can be found by searching 1957 Chevrolet transmission on eBay. | | | | | Joined: Apr 2005 Posts: 2,097 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 2,097 | Anaheim Gear has them for the SM318 (55 up) they may have the earlier style also. 800-477-1103

Jeff | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | I'm pretty sure the tranny is original 53'. Got the truck out today for a few warm up laps and it is running OK but not fantastic after sitting covered up all winter. A great deal of humidity has collected and minor rust is showing up. darn. I jst don't feel like puting the spit shine on it again this year.
Thanks for the info gentlemen. | | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | Dave,
Check out the Filling Station part #RW-453. These are the two synchronizer rings needed at $35 each. Are you looking for the whole assembly with the synchronizer drum and synchros?
I rebuilt the 3spd transmission in my '53 several years back at $90 for the full kit, minus $20 each for the synchros. Seems prices have skyrocketed in just a few years...
I have the shop manual for overhauling scanned if you need it. PM me if interested with your email address.
