shnookie,
I am in the same boat you are. I am also trying to complete a RUCC kit that has been under assembly for about a year and a half. I ordered the kit in 99 and took delivery on July 4th, 2000. After arriving at Roger's shop (13 hours of driving) I found that only a little over half of the kit was present. I accepted the kit at theat time but demanded an IOU for the outstanding pieces, it took many months to collect the remainder. At this point I have everything except the headers which have been on order for 14 months. Roger does return my calls, but as of yet will not give me any date for completion. Of course, my car is only collecting dust while I wait for headers. At this point I am willing to wait a little longer but am considering alternatives as we speak.
I don't have any info that will help you out directly but that's my 2 cents worth from a fellow RUCC owner.
