I've bought several sets of gears from him and a couple pinion supports. We've put the gears into everything from a 3300 door car to a 4.50's dragster. The gears are Italian made by the mfg. who makes Feraria gears and so far no failures. I don't know about the new Alum bolt thru cases he sells, i think they are made in China. I would say over the yrs. i've had good luck with his stuff and no problems with his shipping.
