Finally got around to getting my gauges transferred from old car to new, i designed and 3d printed a gauge cluster that basically snaps into the interior and surrounding panels. I had to cut the original sunglass shelf off the cigarette & button thing, which i did carefully with a coping saw, the cluster has plastic tabs which slot behind the cut down piece, and a lip which slots into the OBC unit above.
Fits 3 52mm Gauges
Please note, because the tabs on the bottom of the cluster are not symmetrical the object will need to be mirrored to work on a left hand drive car. Was designed to work on rhd. IF i get around to it ill make a lhd version, and a 6 gauge cluster that replaces the OBC for both variants
