Good luck! It does look like a pretty solid pig. I just wonder why you will be taking a fairly well worked running 40 (by the looks of it) apart just to have two projects in your driveway? Try keeping both? Hope it goes well. (More pics the better!)
My 78 Australian FJ55 has hand cranking tailgate, front disc brakes, and retractable front seat belts. It didn't have middle lap seatbelts probably because the bench had already been removed. (It is possible the disc brake front end was an add on by previous owner).
