I am looking at buying a muncie trans for my 69 velle I would like to decode these two transmissions that I have found. One is a 3925661 the other #'s on it are 39821 and 3088336 and it doesn't have a ring on the tail shaft. The other trans is a3925661 with a date code of pod08b with a 26 spline single ring shaft.Thanks for any help you can give me.

3925661 is a case number for 70-74 model year
No groove may be a M22,unless made up from parts
3088336 is the Patent number
P0D08B:
P=Muncie
0=1970 model year
D08=April 8th
B=M21
(1 ring shaft is also for M21)

i believv that the rings are for m20 and m21. but they did make big shaft fine spline m21's and vice versa for m22's

I thought the rings were on the input shaft :confused:
You aren't mistaken Dale. But it's still good not to have any rings on your tailshaft.:D

You're right, might be mistaken for a bulls-eye :thumbsup:
