S12 Rear Sub Frame Poly Bushes?

[Dazmans12]

Hi
Well forgive me if this has already been done, a lot. I ve been away with work so am now doing some catchin up.
I am looking at repacing the rear sub frame bushes with Poly Bushes. think over 20 yrs has done me very well, Have replaced most bushes, some with poly, with the help of 'Concepta tuning', who have been very helpful in sorting out various parts for both my S12 & S13.
I did my S13 about 18 months ago & It made a hell of a difference, that was driftworks who supplied those. But they didn't do S12 ones at the time.

Anyone know where I can get a set from please?
