If you want to buy a cheap angle grinder from Harbor Freight ($15) and some cutting wheels you could just hack those shackles into what you want. You could also just slip them into that next bolt hole and cut off the excess. No need to order any new parts....

You could also play with removing the transfer case drop or just swap it out with some washers instead. You might need it at all.

you will want to deal with this asap. any vibration is a bad thing. it will lead to diff leaks and pinion bearing wear. drop the shackles and lower the pinion input. it will steer better as well.

Thanks again for all of the comments. I didn't get a chance to take a better picture of the angles, but it seems moot anyway. I'm going to order some 5" shackles, tomorrow. I'm not going to expend any time or spend any money farting around with those crappy shackles. I'm also looking at getting a Tom Woods SYE kit. I don't mind spending the money for this, I just keep telling myself I won't get carried away.

Once I have the new shackles in and the wedges pulled out, I will reset the pinion angle and then decide if I should lose the TC drop. I need to check clearance between the top of the TH350 and the floor. I may need to compromise the drop as suggested.

I will post an update soon.

and holy fricking shackles..... I would remove it ALL....shackles, shims, and tcase drop and take it for a drive and see how it drives, my guess is it will be fine.... removing it all will basically bring u back to stock.....unless u hve lift springs in there which it kinda looks like u do, not flat enuff to be stockers.... it will be a trial and error thing
Yeah they must be lift springs. The current measurement to the rocker is 24.5". The crappy shackles only account for 1 1/2" lift.
