I have a 1984 with an automatic and I believe all of their gears were 3.08 that year, I cant tell because my car is at the painter's. I have a new 97 rear end for it but it has 4.11's in it. I would just like to know what kind of combination of boots to use since im not really a tranny/guage man to figure it out. If the tire size matters I upgraded them from the 14's to 245/50/R16. Thanks for the help guys.
