I pulled a 5” driveshaft out of a 2500 dodge truck with a 46re trans that was at a wrecking yard, took it to Inland empire driveline with measurements and the slant 6/3 speed driveshaft and said make me one out of these two. He shortened the 5” to 47-3/4” which gave me 3/4”-1” of slip at the tail shaft and put in a combination joint that was 1350 on one side and 1310 on the other. Easy peasy. And cheap.
