build codes and gear ratio's available on '89-91 2wd suburbans
« on: February 20, 2010, 08:47:35 am »
hey guys,
 does anyone have the build code #for the different rear end gear ratios that were installed in 2wd 1/2 ton suburbans from around 88-91?
 I have 2 burbs and i need to know what gear ratio's i have so i can decide what rear im gonna use.

 Thanks Guys,
