QUAIFE in the past has made their ATB for "Renault 30 / Alpine (UN1 gearbox)" applications. Maybe someone can verify for sure that the differential from the R30 is thesame as the DeLorean. If so, I have contacted Quaife America and they would be willing to do a run of this part but require a minimum of 30 units tobe purchased (50% deposit before they will build the parts). Cost would be about $770 each + shipping. You install it yourself. See: http://www.quaife.co.uk/product/atb.htm Anyone interested in a group purchase? For those of us working on hi-po engines, or conversions this would be a very nice addition.
