    I've read on line (so its gotta be true!) that a driveshaft from a 94 and up Blazer 2wd 2dr, is the right fit, and can be used for a 700R4 transmission in a 79 Z28. Does anyone here have experience with that? Different yokes? I havent measured anything yet, hell the engine and transmission is not in my car right now. But I may have access to a 2002 Blazer 2wd 2dr driveshaft, what do ya'll think? anybody? Thx hope ya'll are staying safe out there.

    If it's 45.5" long from center-to-center of the U-joints. It will work, lengthwise.
    (A factory TH350 Driveshaft is 48.5" long and the 700R4 transmission is three inches longer so your original can be shortened 3".)

    You might need a conversion u-joint at the rear to match the pinion yoke if your using the Blazer driveshaft.

    Thanks for the info, seeing as how I dont even have a driveshaft, I think this might be the way to go. Appreciate it.
