    This was the most inexpensive gearset I could find but I have to say it looks first rate and fit perfectly, only time will tell if the material will hold up but so far so good after a few hundred miles in my 67 El Camino.

    Nice gearset

    I used this set in a Muncie M20 rebuild and have about a thousand miles on the tranny in a 67 El Camino. So far so good. This gearset looked as nice as any of the other more expensive gearsets I've used in the past and went in with no problem. I gave 5 stars for everything but only time will tell
