Just wanted to add to the collective knowledge. Car is a 65 Skylark 2D HT, GS clone in appearance only. I've added 17x8 wheels with 245/40/17 tires, power disc brakes from a 2002 Camaro and a couple small items. Still has a full size spare in the trunk and 2/3 tank of gas. Engine is a stock 73 model 350 w/manifolds and has the ST transmission. Scale says 3560lbs.
