Just looking for opinions here. Working on my 36 chevy pickup,and once I got it fired up and going I found the rear gears are way to tall. 70 in 3rd start loosing speed in 4th, and who knows where 5th is. I also have the correct rear end but it is 4" to narrow. OK opinions, would it be less work to just cut the axle tubes and swap the whole pumpkin or just change the gears out. Everything is pre-setup one way, time consuming the other.
