Default Axle swap questions

I recently broke the welded 7.5 in my Bronco2 so I rebuilt a new 97 Explorer disc brake 8.8 for it. I stripped the housing clean of all brackets,installed new gears,diff carrier,locker and built a truss.I went with Ballistic Fab for my spring over install kit.

Here is my questions...

The new spring perches have 3 holes in them for the leaf spring center pin. Is it ok for me to use the forward facing hole instead of the center hole to move the axle about 1" to the rear? There wouldnt be alot of perch under the spring on the front side doing this so I didnt know how this would effect spring wrap up.Or is this not even possible because of the U-bolts?

After I did my 5.0/c4 swap the pinion angle was actually in the positive on the 7.5 and I was using a modified stock driveshaft with a double cardon at the front. Truck drove fine and never had any problems. I havent built a new driveshaft yet for the 8.8 and I was thinking this might effect how I set the pinion angle.Yes?No? Should I use a shaft with a cardon joint again and just weld the perches so the pinion is in line with the shaft? Or should I use a shaft with 2 u-joints and set the pinion angle to a certain degree? And what is a proper pinion angle setting for a setup like this?
