I doubt they are a rebody also. Just sourced the same axles. Dodge was using a d60 front, d70 rear, np205 at that time in the diesels.
t-case was the right drop, Grizz go with a divorced, t-case? Would make different engine / trans options easier to build.
Wheels, oem replacment, hubcaps could've been bought at the Dodge dealer.
Girzzly's were longer than a regular truck, make no sense to cobble a frame.
Front shock geometry doesn't match a Dodge either, my 92 w350 single wheel is in front of me now.....
The silver truck has the Selectro locking hubs, they went away in 89 or 90. They take a different front hub than a Warn lockout. Actually they are full time hubs, with a lockout instead of a splined end cap. I have all 3.
What was the most common engine / trans Grizzly's came with?
