Bttt.
Gives a 4th and 5 overdrive. Nice lets u run 65 70 no problem. Great for driveabilty of a stock a. They sell a conversion for mec brakes. But if u have hyd its easy.
Does that give you any lower first gear and any overdrive in fifth gear ? Sounds like a fair price and a neat modification for a heavy car...or even a light car with tall rear gears....a freeway flyer....
