I'm using the Doetsch and they're pretty good.
15x7.5 rims? Odd size. 15x8's are more common. I can't see why you wouldn't be able to run them though.
One thing: you're going to lose a lot of "oomph". You're going from 29" stockers to 33" without regearing and the most likely gearing you got from the factory in a 3.0 2WD is 3.73 ratio which is pretty weak for 33's. 4.10 or 4.56 would be better. As long as you know, your 3.slow is going to be 3.slower, lol. I have a 3.0 also and I regeared to 4.56 but that's a lot of extra expense and work. Just something you have to think about.
Spindles are not a "simple" bolt on. You have to address the brake lines, grind on the lower a-arms a bit, etc. Read all the posts you can find on here about spindle installation before you get them. Otherwise there could be some unpleasant surprises!
They're a real good way to lift a 2wD, though. I love mine and with a 2" torsion bar crank also I fit 35's with just a little adjustment of the flares (and my front valance is removed also). 33's are a "slam dunk".
With 35's, 2" crank, and the spindles I have 16" between my front crossmember and the ground!
