I think this might make for a decent sticky...
Searched for this but couldn't find the specifics...
I know the NV4500 to dana300 can be a direct bolt up but only with certain models and I want to clear up all the possibilities.
What year model dana 300s can be used on the different NV4500s.
I want to know if all year dana 300s are the same?
Are all of them passenger drop?
What NV4500s have what output shafts?
UPDATE for the NV4500HD to Dana 300
I got it figured out. I was able to speak with John White of JBConversions and the kit (http://www.jbconversions.com/pages/p...300/plate.html) comes with the input gear(with no additional charge, must specify when ordering what spline count) for the 29 spline nv4500hd. Also, with the rotation plate/input retainer combo that is in the kit is enough spacing for the extended output shaft of the nv4500hd, so no cutting is required. Thanks guys for helping me, sorry for the run around, i just heard too many contradicting stories to understand what was going on.
