I have a 1987 Chevy c30 with the granny low 4 speed manual transmission. Of course I never use 1st gear. I would like to do a swap and put a 6 speed close ratio manual transmission in it. Anyone had experience or know what transmission will work for the swap? 1987 Chevy c30 flat bed with narrow dually rear end, granny low 4 speed manual transmission, and a radical 355 motor. Trying to make it more road friendly as far as shifts go. I'm thinking the 6 speed swap will give me the road ratios I need and retain my pulling power. Thanks
