need advice...
I have a 1988 GT with a t-top roof. It's a 5 speed and mostly stock with almost 188,000 miles. I have a few questions... 1. I have a stress crack in the frame by the windshield. What can I do to stiffen the structure and prevent further damage? 2. I want my car to accelerate better, so I'm thinking about new gears. I'm pretty sure I have a 2.73 rear, and I bought 3.73 gears for it. I do a lot of highway driving, so will the 3.73's be ok or should I swop them for 3.55's or something lower? thanks for the help ------------------ 1988 GT 5-speed K&N filter 2 chamber flowmasters |

get a pair a sub-frame conectors to stop all that flex. With stock 225/60/16 tires(i think thats right) and a .68 over-drive(i think thats right too) you will turn 2243 RPMs at 70 MPH with 3.73s. You will turn 2134 RPMs at 70 MPH with 3.55s.

Thanks, I think I'll go with the 3.73 gears. Does anyone know where I can find the gear for the speedometer so it won't be thrown off?
