I've settled on 49 5/8" planned for the disc to disc diff width....

The 8.8 I'll be using has a 2" pinion offset to the passenger side. Since these cars come with a similar offset (something like 1 3/4") I'll likely take the same off each side. The 8.8 is 59.5" disc to disc, so that will mean 4 15/16" off each side. The minimum cutoff according to Dutchman Axles is 3.5" so I should be fine.

Some revision: For simpler calculation, I've adjusted the D to D width to 49 1/2" That's an even 10" off the 8.8. The A Body offset is 1 3/16" to the passenger side according to Dutchman and confirmed with a measurement. That's more difference than I like so I'll be going with different cutoff amounts. To adjust the 2" offset closer to the 1 3/16" mopar setting, I'll move the center over 3/4" to the driver side. The passenger axle will be shortened by 4 1/4" and the driver axle by 5 3/4".

For reference the length of the 8.8 tube outer to outer is 56 1/4". Dutchman requires this measurement.

Edit: What they want is backing plate outer flange to flange. Edit: It measures 54".

(Boring stuff, Its just handy to have the numbers here for reference)
