I thought at one time a found a nice big driveline database, but i cant seem to find it when searching. I need a driveline for a 1990 extended cab that was originally a 2wd, now converted to 4x4 with about a 5 inch lift. I got one from a regular cab 92 i think, but after buying it i forgot i needed one for an extended cab. Is there a really big difference in driveline length between the ex cab and reg cab? Can i make this one work till i get the ex cab 2x4 line shortened and a long slip put in?

 

or will a driveline from an 88 ex cab work on a 90 ex cab?
