you can run a 2.5" exhaust on the passenger side but the inner side of the exhuast pipe should be flatened a little to give a little more space between the dana 300 and the pipe.

i have mine installed in a 74 j10 with dana 44s front and rear. the driveshafts will bolt right up. the rear shaft will work fine if your running a 4" lift. the front will work fine if you are stock height. a little difference in height, the drive shafts will probably still work but you could run into something breaking if the suspension is fully compressed (rear) or fully extended (front) take the time to do some measuring.

i'll be installing a set of j20 axles in my j10 in the next week or two so i'll post up about the driveshafts then. i have yet to run mine so i have no feed back on that, yet.


Here's where I'm at with it. 78 Chief, rebuilt 401, rebuilt T400 w/ novak adapter to D300. CUCV tons, Dana 60 front/14 bolt corporate rear. 6" BJs offroad springs & due to D60 being spring over I flipped back.

Basically I'm sitting on 11" - 12" of total lift on this rig and what I didn't plan well for is driveshafts. I'm looking for any and all help on driveshaft options w/ the D300 and the best position to clock it?

Any help will be rewarded with many thanks!

How do you know your driveshafts won't work? have you already put them in and flexed it out? I recently put a new shaft in mine and I had to stretch it out before I found that I had an issue.

You could also run a bigger yoke and get a better angle that way from the joint.
