hi can any 1 give me a close weight of a 69 b body minus motor , trans,and interior thank,s

A RR will be less than a Charger.

I would say about 3800 average complete and about 1000 less with all that gutted. Remember the shipper will likely charge extra for a non running car.

I would think gutted no front cross member, steering. gas tank, rear end, springs wheels and tires less than 2000 take out the windows and doors and less than 1800.
