Passenger drop...driver drop...whatever. If you can't find one, then make one! (takes a big lathe, though). This one started out as a drivers-drop Ford HP housing just like yours. I cut down the passenger-side tube to the same exact length as a GM low-pinion. Then I made a brand new tube for he driver-side, also the same length as a GM housing. Put it all together...welded it up...stuck-on the innner-Cs...and TA-DAH! The result is a high-pinion, passenger-drop, Dana 44 built to GM specs. It uses stock length GM shafts, either GM, Yukon, G2, USA Alloy, RCV, etc. The only Ford parts are the inner axle seals...
