The number you gave is for a Muncie 4speed tail housing. Can you get the numbers off of the main case? The dealer will not be able to get you the input, you will have to buy it aftermarket or find someone that has NOS.

The 3925660 main case was used from '68-'70 with a 1" countershaft; your tailshaft housing is from a '63-'65 trans, so it's a "mix" of parts. There should be a VIN derivative stamped on the right rear vertical flange of the main case along with a Muncie date code - the VIN derivative will show what it was originally installed in.

If 4th gear lost 3 teeth it probabily took out the cluster also. If that is the case you are getting to the point that it is not worth rebuilding unless the price of cluster gears has come down since I bought one. It appears to be a basket case so you will have to identify which gear set is in the case. The easiest way is to take it apart and count teeth. Don't go to Chev. to get prices there are some guys on the site that will be cheaper.
