Hi all. Just finished installing new axles, hubs and spacers in the T/C. All the old stuff was well worn. Dave Meisel in Troy, Michigan is offering a up-grade rear axle kit on E-bay. After much discussion with him I bought the up-grade. A friend of his designed the kit and races his Europa SCCA with this up-grade. Dave has been doing the kit for a few years now. He offers a hardened 3 key way (replacing the splines) axle, new hubs and spacers. I sent him my up-rights so the spacers were an exact fit between the inner and outer bearings. Also sent the old axles since he uses the old u-joint yokes welded to the new axles Production took 4 weeks and I think it is a good product. I change out the wheel studs to a 12mmX1.50X41mm Dorman stud but the original 3/8 studs will work. The axles were a mild press fit into the up-right bearings and the retaining nut is a better design using an large lock washer (No more lock tab). Had to do some light sanding for a good hub fit on the axle shafts and it appears the 3 key way fit for axle to hub is stout. The hubs are a bit larger and you do not need the spacer that goes between the original hub and outer wheel bearing. I have about 100 miles so far on this set-up and all seems ok. Installed Precision brand #344 u-joints, new wheel bearings and inner seals. Of course all is new so time will tell... Tom
