.......... Now you have to see if its a 904 steel case.

This is one of the HEAVIEST transmissions I've ever carried (but it's been a while)

It seems to have rusted up almost overnight

Is this T10 a mutant, with the alum tail and the steel case?

Trans-man says T10 two inches longer at the case; ear to tail case end. The gears are out of the M21; could the length variable be the size of the rear spline ?

I just measured a Muncie and a Super T10. There is a 1/2" difference in length from mounting flange to the rear seal. Your Super T10 is not a bastard. A lot of those transmissions came with iron case and aluminum tail shafts. I have owned bout 30 of them over the years.

Thanks Matt, can I get away with my original driveshaft with the 1/2" difference?

According to the info i found, 6 grooves mean it has a 2.88 first gear, mine has 6 and i really hope is not a 3.42.
this is the ratios i found,
Number of ID Groves, 1st 2nd 3rd 4th
2, 2.43 1.61 1.23 1.00

3, 2.64 1.75 1.33 1.00

5, 3.42 2.28 1.46 1.00

6, 2.88 1.91 1.33 1.00

Your number 5 and 6 are backwards Blade.

Chris- I think you could get away with your standard driveshaft.
