Drive Shaft differences

[brianrbull]

I currently own 2 CUCV's 1 M-1008 and a M1031, The M1031 has the much sought after GL mod....
There are some drive shafts for sale in the classifieds, I need to know if there are any differences between the drive shafts IE Length, Yokes, Spline count ect.. I would normaly just go out and measure it myself buy I am 10,000 miles from my truck. (In Afghanistan) Any help would be greatly appreciated .

The 1009's have completely different driveshafts. The rest should be interchangeable for the most part. My M1028A3 (with dana 70) has the shaft out of a M1008 (GM 14 bolt) currently in it. Be advised though the wall thickness is thicker than civvy counterparts and will cost more to have a bent one fixed as it takes a special tube to do it right. Last, the M1028A2 has a NP205 transfer case. That shaft will be different.

My 1031 has a different 4x4 shift lever than my M1008...I am assuming (I know who assumption is the mother of) that I have the NP205, My contact has the PTO Gennie in it. so would that mean that I too have a different type of shaft? and is so would it be possible to just change the splined portion of the shaft? According to the TM there are several variations for the driveshaft. my truck shares the shaft with the M1028a1 Type "F" Shelter Carrier w/PTO. is the only difference wall thickness?

The 1008 and 1031 have different driveshafts. They have different transfers, 208 and 205. Easiest thing to do is take your bent one (when you get back from taking care of business) to a driveline shop and have them re-tube it for about $120.

Yep, if you have the PTO, you have the 205 and it will be different. I'd either re-tube it or you will pay the big $$$ for one from somewhere like CSI.
