TH 400 speedometer drive gear clip?


Aug 8, 2011
I found 2 different clips that look the same but one is wider and since my race trans came with no drive gear I need to install one.
Anyone know which one is correct for the TH400?
The GM part numbers are below each one
5/16 in. wide gear clip. Replaces OEM part 6261781.
7/16 in. wide gear clip. Replaces OEM part 8628557.

Everything I'm coming up with for M40 (TH400) is GM p/n 8626089 for the speedo gear drive clip from 1960s on up to the 3L80. It was 15 cents MSRP back in 1972!!! :) Not so cheap anymore.
