well as many of use with t-5 trans and 3.73 gears know gm has stoped making the 21 tooth gear for our cars. but, they still make the 21 tooth for the s-10. so what I did was I ordered the 21 tooth for the s-10. then I dug up an old 22 tooth I had and turned it down so that teeth were no more. and the gear was now the same diameter as the part that stuck out past the teeth. then I drilled out the center of the 21 tooth s-10 gear so than I could press the old 22 tooth in to the inside of the 21 tooth gear. It sound kinda funny but, it worked and looks great!

 

LOL! Good job man!! I always say, "the mark of a true genius is the ability to improvise"
