well finally did it, my rear gears ended up cracking a few teeth off so i had no choice but to install the 3.08's and i did the 5 speed while i was it. well i can say is i should have done this a loooooong time ago. the truck still does burn outs with the stock 235 and i can cruise at 65mph at 1,800 rpms. i got the truck up to close to 90mph just to see if it would do it. and my MPG doubled!!!!
so 3.08's and a 5 speed are PERFECT!!!!!!!
