why not just buy the cab, put it on a single cab chasis.
i see em all the time, i drive a single cab 82.
if i were gonna do a 4 door id build some sort of wagon instead
just spent a year in iraq and saw some nice frontiers, hardbodies, and 710s also 89-95 yotas, and tacos that were all double cab 2wds i'd love to be able to get my hands on one...
