The new Hursts aren't as nice as the old ones. It looks like the stamping dies are just tired. Also; B&M who owns Hurst firmly believes that all M22s came with TH400 outputs...this is NOT the case. Not only did M22s come with 10spline inputs at one point; you could also get an M20 in 1971-74 with a 32 spline output.
Thus; if you want to buy a NEW shifter; get a Long (brand) shifter; when you compare prices, don't forget to add in Hursts 'installation kit' to make it a fair comparison.
