Re: Weight assuming from all you removed (engine, transmission, interior etc. etc.) my guesstimate from what I see in your last photos would be between 1,700 to 1,900 Lbs. Not including the frame of course.
If someone would ask me what the complete rigging weight would be (if transport would be required to another location) I would say rig for 4,000 Lbs to be on the safe side.
Quite a project you have undertaken there! Wishing you all the best for the remainder, must be fun doing and so rewarding once finished. Do keep posting with lots of photos as you go on.
