This is not my jeep, but we did build it for a customer.
1961 Willy's tub and rear frame. Fully modified frame from the fire wall forward. Custom made transverse leaf front suspension. Dana 60 axles front and back (rear has factory locker) . 1993 5.9L Cummins TD with NV4500 transmission. 200HP and 440 ft/lb of torque. Many more little hand made parts as you can imagine the CTD did not just drop in.
It's blast to drive!
