Projects 1960 Impala / Belair bare shell weight

hey guys, anyone have an idea of the weight of a 1960 impala 4 door sedan/ Belair body shell?
It's just I'm looking at getting mine on a rotisserie for body work. the weight I mean would be a completely striped out shell.

 

I think the kerb weight was around 3700 to 4000 lbs, so start subtracting weight of each component. Engine & trans are 600#s maybe? Front suspension is maybe 300? Rear axle? Seats are heavier than you think, so? Hood and trunk lid, maybe 100 each? Doors, gl***, bumpers. I'm wildly guessing on each component's weight.
