It may not be listed in the guide ,but the ZJ Grands were available as 2 wheel drive models with a straight tube front axle ,as were all Jeep models . there was a fairly strong market for the rear wheel only models in southern states where the 4 wd was not really necessary and the Jeep were seen as status "driveway ornaments ". The Jeep dealership I worked for always kept at least one of each in stock
There may be potential in the combo ,but it surely will not be an inexpensive build to get it competitive .
Do a LOT of research before diving in . It may be wiser, and possibly cheaper to start with a known combo. Look into Billy Nees' posts on "DIME ROCKETS" for some ideas.
