Do you have the Assembly Instruction Manual for 68? I know those tag numbers are set out in the 1969 AIM, but I don't have a 68.

Here are 1969 numbers:

3950356 is for RPO L48, L34, L35, LM1
3946797 is for RPO Z28 & L78
3946798 is for RPO M21 with Z28 and L78
3950318 is for RPO m22 with Z28 and L78

Hope this helps.

Peter,

A friend has a very unmolested 68 L78 with a M22. It doesn't have a metal tag and doesn't look like its ever had a wrench on it. Best 'factory' 68 M22 I've seen in a long long time. There may be exceptions, but I don't recall ever seeing one.

Ok I went out the back today and found my m20 muncie trany
the numbers on the trany are as follows
660 case,vin # 18w360660, assembly date P 8 E 24
it has a steel tag and the number is 3915077
so does the 68 m22 have a steel tag? and what is the number???

Peter,

ALL Muncie transmissions had a Part Number tag from the factory. Most have been lost over the years with rebuilds and what-nots, but if you still have yours, feel lucky!

The original part number for the 1968 M22 was dependant on a few things. First was when it was made. Early 68's had different part numbers than later 68's. It also depended on the rear end ratio. Here's what I have for the 1968 Model Year: (Also note that the M22 was available only on the Z28, L78 or L89 cars...)

Early 68 with 3.31 or 3.07 Posi rear end used the 3919397, which was replaced mid year with the 3932259.

Early 68 with all other ratios EXCEPT the 4.10 used the 3925626, which was replaced mid year with the 3932258. (I have no info on what M22 was used on the 4.10 and why it was different. Sorry...)

I'm not sure of the exact dates of the part number changes, but I believe it was in early 68.

Hope this helps...
