Ford 8.8 axle swap
albsvx:
I'm just curious here (trying hard to cause trouble) ... what do you expect to do with an angle finder, exactly?

Basically,
The angle finder is actually(or the ones I've seen) magnetic and can exactly tell you what your driveshaft angle is and then, along with your pinion angle, you can determine and set the safe operating range of your u-joint depending on the application.
Here's basically how: I would put his jeep on level ground, put the pinion angle gauge on the axle and see what its at right now because he's not going higher with the lift so it should be set the same. The angle gauge will show what we need to set the 8.8 at to resemble its installed position. Then all the other brackets are set to true level (coil buckets, 3-link truss, and the lower control arm mounts). After being welded, the brackets should set the pinion angle damn near exact and, if needed, the lower control arms can be used to fine tune the angle.
This is a good writeup on driveline stuff...

ah, okay, I was under the impression that he believed that his was not currently set right.
for a CV driveshaft, the pinion angle is supposed to be such that the pinion yoke is pointed directly at the tcase output yoke. I wouldn't think that and angle finder would be much help with that, except as you say, assuming that the current one is properly setup.
Ahh, I see, that article is telling you how to do math based on the measurements, even if it's not currently right ... I guess that makes sense.
A few things however that need to be taken into consideration are:
aren't you replacing your tcase yoke with a shorter sye?
is the distance from the axle tube center (or possibly spring perches) to the pinion yoke on the 8.8 the same as on your D35?
Axle:
Yes, I am getting a short output yoke for the T-case. It's only going to shave off about 5/8" of length. From the writeup's I've read on the swap, everyone uses the same drive shaft they used for the D35. The hard part is going to be getting the position and measurements of the brackets exactly where they need to be.
albsvx:
Yes, yes it is.
:)
It's certainly more than I'd have the patience for. :)
