'70 Pontiac lemans?
My brother(a mechanic/specifically Pontiacs) said that a 4dr. '70 Lemans would be lighter that a two door because the door panels add the extra support other than a steal support under the car(or something to that nature).I have found a '70 4dr. Lemans,
thats a keeper, but i dont know about the whole 4dr being lighter tho, i think the 2drs are worth more in stock/restored form, but if ur going to drag it, have fun, buy it
