I have most of the measurements I need but my existing bushes got ruined during the removal process so the aluminium tube is not attached to the steel outer (I burnt the rubber away to release it).
If anybody has a spare rear subframe mounting bush could you just quickly measure how far the aluminium center tube sticks out from the top and bottom of the bush (in comparison to the steel outer case).
Also when I may be able to get a few sets made when I have finished the design and tested them if anyone is interested.
Cheers
ETA a quick pic of the measurements I am after:
