78 Chief W/T - 401/T400/D300/12" lift - DRIVESHAFT HELP??

Here's where I'm at with my rig.

78 Chief S W/T , rebuilt the 401, rebuilt the T400 w/ novak adapter to D300.
CUCV tons, Dana 60 front/14 bolt corporate rear. 37.5 hummer 12 bolt wheels and tires.
6" BJs offroad springs & due to the D60 being spring over I flipped the back.

Basically I'm sitting on 11" - 12" (estimate) of total lift on this rig and what I didn't plan well for is the driveshafts.

I'm looking for any and all help on driveshaft options w/ my setup, the D300 and that much lift??

Certainly someone has this setup, or similar and has some advice on driveshaft options for it. I'm lost and the rig has been sitting for a year, I've been tied up with Navy duty and I wanna get this thing done NOW. I only lack driveshafts and shocks and I'm in the wind.

Please help a fellow Chief in need!!!

*Will post some pics asap*

This is very close to what I plan on for my chief build up with a few differences. I'm gonna keep spring over but 2" springs at most, match the rear. I will probably run a 203/300 doubler. With this height my drive shaft angles shouldn't be a problem. I would look around at what the mud boggers are running and check out high angle drivelines. High angle drive lines makes an extreme angle shaft that I think can handle up to something like 42 degrees. http://www.highangledriveline.com/products.html

If you have to get shafts made,talk to the guy first.
You will want to have the correct pinion angles and shafts.

Sorry, let me clarify that part, ill def have to get driveshafts made, just not sure what the options are with it. Almost afraid my angles are so bad that something drastic will have to happen. I just have no driveshaft knowledge so im likely thinking the worst. I love this truck and need it to LIVE!!!

The front is going to be an issue at that height. The best thing to do is lower the truck [spring under]. The other option is to lower the drive train [motor mounts and X member]. I'm salvaging a mud truck now that was 4" over axle and even with a 4" drive train drop the front DS wasn't going to work. The last option is to cut/turn the front differential to point it at the Tcase and have a good CV front DS made.

Too much lift

Too much angle for the stock system. I've never done this much lift but the one feasible options.
Clock the T/C straight down with a clocking ring to drop the drive shaft angle.
I hope these are top loaded differentials?? The front driver shft will always be a challenge if you oplan tooff road it have double shafts built you'll need them,.

Just My opions.

If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

Definitely a candidate for Tom Woods high angle shafts.
