Randy, I like ANY Jeep kit for parts, as well as the Revell '99 Silverado (for the LS engine/tranny), the old Revell/Monogram 1/24 4X4 Chevy/GMC pickups & Blazers (for the best transfer case in scale, the venerable NP205). The best Dana 60 axle lives in the Revell '68-69 Chargers (the newish Hemi Dart probably has the same axle).
The aftermarket is the best place for tires, and the rest is scratchbuilt
