Going over the ol' Saginaw I confirmed the deatails of it, '75 Monza/Vega HM code 3.11:1 1st gear. Now I need to work around the speedo gears. I don't want to crack the main case & tail housing apart to change the 7 tooth gear. I looked up on a few web pages to see what driven gear I need just to see that it don't exisit (15 tooth.) I'm running 2.73 gears with 235/60/15 tires & need to see which driven gear/gear reduction combo I'll need. I have the driven gears from 18 to 22 tooth so all I'll need is the reduction box. Any ideas of what is out there?
