If the 8.5 has 1/2 larger axle tubes couldn't 7.5 axle tubes be welded on inside them with perhaps some additional material to make up the difference?

I never understood why GM didn't put the Dana 44 in 4th gens. SLP had them made for the 3rd gen Firehawks and you could order one from SLP, Summit Racing, or straight from the GM Parts Counter as it was listed in the GM's Performance Parts Catalog until 1997 or 98. Although it was listed for a 3rd gen, it would have been easy to make one for 4th gens. They already had a cast center section that utilizes a torque arm. Adding provisions for 3 channel ABS and putting 1 1/2" longer axle tubes wouldn't pose much of a challenge. IMO they probably would have saved money in warranty issues.

Even the Borg Warner 9 Bolt (BTR 78 series diff) used in third gens and numerous Aussie vehicles would have been a better choice.
