wow.that,s a lot of tinworm.Maybe 1500.00 if the interior nice.If the original engine is there,with carb,and it turns it may be a good parts car for you GT guys.I always like big car performance.A 6 barrel GT with console would be heaven.I had a road collision once with a severe road depression and yeah,that looks like a broken ball joint.all that rust converter can,t hide the severe rust.Maybe the dash isn,t cracked which is a problem.Go down with 3500 but wave 2000 in front of the owner and they might take it.That,s just a lot of rot .B.B
