Detroit TrueTrac on Jeep WJ with Quadra Drive

Hello All... I'm a rookie at this so bear with me....

I have a 1999 Jeep WJ with DANA 30 3:73 gears up front. My Vari-Lok differential went bad (grinding, sticking) so I decided I would swap it for a Detroit TrueTrac. Purchased TrueTrac from Summit Racing (part # 912A314), dismantled the front end and placed the TrueTrac (that was the easy part). When I tried to install the stock axle the driver side was short and the passenger side won't go all the way in. I had the impression that the TrueTrac is a direct swap for the Vari-Lok and the stock axle should plug in. It wasn't the case. After a while I got frustrated so I returned the TrueTrac and purchased a Vari-Lok stock replacement. My question to all you experts is, did I need to get after market axles to make the TrueTrac work with my QuadraDrive?

Question 2: On the Vari-Lok Differential, is the plenum a vital part for the Vari-Lok to function?. It seem to me that for $130.00 for a piece of metal shielding is a bit too expensive.

I would give Randys Ring and pinion or one of the others a call. Its a shame the True Trac was not able to work as its a great unit. I had one in my old XJ and loved it. Did you try putting the axles in after you removed the TrueTrac?
