Both

By whipping the rear prop and back casing off the transfer box I have a dummy gearset we made / modded, which gives it RWD only.

Takes about 1/2 hour on my 2 post lift

I did this because we have some events up here which are 2wd only

It's a Cosworth Scorpio back end with 3.9 7.5" diff (2.3 Scorpio) with LSD 108mm Cosworth rear shafts, and Vented Cosworth Scorpio Rear Brakes, Sierra Cosworth 4X4 Front End with Cosworth Scorpio Front Brakes / Calipers, 3.9 (2.0 4x4 Sierra) front diff, Electric Pumped 4X4 Sierra Brakes, Hydraulic Clutch conversion, and Ford 909 Bilsteins with Faulkner Springs for Gravel set up. No ARB's Compression struts on front which adjust castor and sliding top mounts for Camber Adjustment

Did you get my pm earlier?

Cheers Dave
