Hi guys,my names eric,im from sydney australia,been modellind for about 25 years.i am a crazed peterbilt nut(i think tim ahlborn can vouch for that! hehe)anyway,can anyone tell me if there was a run of this particular kit that came equipped with torsion bar rear suspension? i ask because ive seen a few built up clunkers on e-bay and they appear to be un-modified but have this rear suspension.any help would be appreciated,thanks ERIC
