that the only set of DCOM's I've seen but that is a new thread,

Rebuilding a set of DCOE's can cost about $300 if you have to replace all the jet, tubes and venturi plus rebuild kit and shipping,add 200 for used set and shipping,and new don't seem so dear, reoriginals has a 45's for $380 less linkage, just make sure the used don't have worn shafts.
