If you know how to weld, get the 8.8.
8.8 pros-
31 spline shafts
disk brakes
huge axle tubes
8.8" ring gear (go figure...)
Less expensive.
Stronger
cons-
c-clips
axle tubes need to be welded to the pumpkin (easy to do)
5/8" narrower on each side (no big deal)
D44 pros-
direct bolt in
(im not sure about the axle tubes-ring gear sizes etc so if anyone could fill thsoe in that would be great, but im sure the 8.8's are bigger.)
no c-clip axles
Cons-
more expensive
drum brakes
weaker 30 spline shafts-still way stronger than a 27 spline d30 or chrys. 8.25
The way i look at it is, if you want to do the swap right you need to cut off the perches and reweld them so your pinion is pointing directly at your driveshaft, this way you can use huge antiwrap perches to help with axle wrap, and not use shims. So why not just go w/ the 8.8?
