haha good luck finding anything on the net about it. best plan is to just get hold of a 60 series body pan and lay it on top of that chassis then start cutting shit. Ive had a look at doing this before. was planning on doing it to coupe, its def doable but you would want to ditch the factory rear spring towers and maybe put bags in there as they stick up heaps, think ive got a pic of 140 series chassis
60 series chazza
140 series chazza
and more 60 series chazza, featuring the infamous sheepers!!
check out my build thread there's quite a few more pics of chassis
