I have a 1994 GMC 1500 2WD with a 3.08 gear and open diff. I want to install a LSD and 3.73 gears but GM no longer sells the module to correct the speedo. I know some of you have altered these to fit your purpose, can anyone sell me the correct module for this conversion ?? Thanks!
I know a member here who does this . and has extra modules in stock .
