Cambridge Motor Sports from the UK use to have a complete conversion but no more, I emailed them three weeks ago about this and they replied that thier conversion ended up not reliable. I saw that Goodparts is now making a third member conversion---I would have rather seen an axle and hub conversion!!. You always see mention of the corvair or datsun axle conversion but never any detailed instruction on how to do it??, is the Moss a complete conversion--axle and hubs and how much?, I have never seen it advertised by them.
