When I ditched my Peugeot, I kept the stock crossmember. There were several unused holes in it from the factory, so I tried a TJ transmission mount. it fit both the crossmember, and the ax-15. It ended up offsetting the transmission so i flipped the crossmember and now it sits dead center in the transmission hump. You will lose the exhaust hanger, but I ended up cutting that plate and redrilling the holes to fit between the tranny and tranny mount.
