I have never seen a discount code for GV. I have paid list price for 2 of them.I am ready to order an overdrive kit for my 67 GTX from Gear Vendors, does anyone have or know where to find a coupon code? I just installed Holley wheels, new tires, and recieved 3.91 gears from Dr. Diff. Thank you!

I didn't do the math for rpm's, just for final drive. I have 3.23's now. 3.91's should result in a 3.05 final with the gear vendor. I put a fair amount of highway miles on and the 3.23's aren't terrible so I figure a little improvement on the highway and a pretty drastic improvement in town should be good. The new tires are a bit taller as well.List for 1, never saw any code. What rpm are you hoping to run at 80mph. GV, 3.73's, 26.5" tires, 3,200 rpm at 80. GV is only 0.78 overdrive.
Here's a calculator that I use. I live in the SW and open interstate everywhere. 80 is slow here. 3,200 rpm for hrs is a lot of fuel.I didn't do the math for rpm's, just for final drive.
