76 J10 - 3" lift and Front Drive Shaft - need recommendations

I am in the middle of a 1976 J10 refirb. After we installed the 3" lift the front drive shaft is now 1" to short. I wasn't expecting this issue with just 3". I'd like to have some recommendations on what to replace it with, there seems to be a wide range of $$$ for these things.

Thanks

Are the springs installed backwards?

Are the front shackles pointing forwards or towards the rear? I am serious, had a similar issue.

ummmm... sitting side-by-side, I don't see a difference between the ends. So how would I know?

Regarding the shackles.. they appear to be facing forward.

Hmmm.. If it helps I recently installed a rough country 3 inch lift on my 76 Wagoneer. Had no problems.

This was the issue I had. Installed the springs on a bare frame without compressing them a bit. Note the front shackle rolled backward. It should be rolled forward at a similar angle.

I just had my driveshaft lengthened by Bud Paulson (J20 Project on here, his member page is here) after installing some lift springs. My springs went from stock to 3.5" of lift and my shaft was a good inch and half too short. Bud also did my front driveshaft a few years ago when I did a shackle reversal. He rebuilt the Cardan joint, lengthened the shaft, put on a long travel yoke, painted it, and balanced it. Even after shipping both ways, that was still cheaper than buying one of the pre-made shafts. Plus you are giving some bidness to a member here.

He also just did a front shaft for Cliff: Read his short thread here

Thanks Rang, I'll keep this in mind when I get back to this part of the refirb. I"m now in another problem regarding my Dana 20 transfer case I'm needing a part for and am getting ready to post about it. <-- seems like I'm doing this a lot lately

That's good to know J20, my son and I had a devil of a time, getting it (shift rod) out and now it has a slight bend, which may have been why it was difficult getting out. I need a new one as I'm not sure this one can be straightened enough for reuse. Seems the tolerance is really tight on these. It's the driver side rear shift rod. Know where I can get one? Summit Racing can't get me on until mid december.

Fixed the issue..... indeed, the springs were on backward, there was 1" difference between shackle center holds and center bolt. Turned both around and it went right together. Sure wish there would have been some instructions that mentioned that in the kit.

Thanks Ristow, much appreciated.
