My search for a shorty D100 is over

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.

Thanks. That is the process I did on my hot rod. I need ~57" and thought of a new one from scratch. 4" rated for 7400 should be fine - I think. Just much more expensive. Not many at wrecking yards here. They wreck them all when fork lifting the vehicles in the yard.
