    The difference is from the length of the tranny IIRC. The auto is going to be longer then the manual, thus pushing the transfercase back farther. It should be farily easy to find a driveshaft at a local junk yard. I am assuming that you have either the 350 turbo or the 700R4 tranny with the NP208 transfercase but if the tranny was swaped it could be different.

    ctfan is correct, but be aware that there are different automatics with different lengths. The TH350 is shorter than either the 700R4 or the TH400. You'll need to get the front driveshaft that's correct for your trans and transfer case. Another alternative is to go to a driveshaft specialty shop and just have a new one made to the correct lenght. They'll likely use the yokes and splines from your old one and weld them to new tubes of the correct lenght.
