Is it possible to just buy the differential? MOPAR 3.73 Getrag LSD Upgrade Kit for 05-14 Challenger, Charger, Magnum & 300 HEMI RWD
I have a local transmission shop that tried to contact you about purchasing one, to replace the one I had sent to them to have a 3.23 gearset installed. They owe me for not the rear, due to complications on their end. I already have the 6 speed challenger axles, and related hubs. I just need the differential. (3.73 gearset I had told them about, seeing as how the 3.91 or 4.10 would be overkill for my vehicle right now). He agreed to it, called your company about it, but hasn't received a call back. His name is Pat Barrett, of level 10 transmissions.
Also, do you rebuild these at all? I still would like to get mine done by someone able to do it, and have the 3.23 diff as a spare later on, in case I have an issue with the new one. Thanks.
