Two piece driveshaft/flip kit question

[tinydb84]

I have a 75 C20 with a two piece driveshaft. I ordered a C20 flipkit through godfather customs.

(BTW they sent parts for a c10 and now won't return my calls or emails)

I plan on just welding a new set of perches 180 degrees from the originals and moving the axle on top of the leaf springs. The directions from the kit say for a two piece drive shaft say to move the carrier bearing up one inch for the 5 inch drop.

Since mine will likely drop 7 inches (due to the leaf spring pack thickness) should I move the bearing up 1.5 inches?

If I move the carrier bearing up vertically it shouldn't affect any driveline angles right?
