al here is your answer right here....crackedback is a stand up guy i have dealt with and trust. at this point you need to take your impossible to deal with gears out. i would pull the center section out of the rear and hook up with crackedback on a gear swap. 3.23's will work just fine for what you are going to be driving plus you can get them in the 489 case like you originally had in the car to begin with. win win deal there......axles will need to be removed by the way, so don't miss the oppertunity to replace all the bearings. this would be a good time as well to switch to the larger bolt pattern axels w/ larger brakes too. this would finish up everything on the rear completly.
