GSF do these: GSF Part No. 31147B GEARBOX MOUNTING-REAR G3 VR6 1/92 >12/97 £15.60 the same part no. applies for the mk3 1.9 Turbo Diesel , made by one of the giant oem producers (did these stay same betweem mk2 and mk3 maybe?) also GSF Part No. 10139T is the other rear mount £36.50 both seem fine to me with a vibra fast road up front, very slight increase in vibration, gear change much better,(mine were shagged/leaking too,)bit more whine fom gearbox maybe, but still wonder if i shouldn't have fitted vibra ones all round though,a la soul 2 soul, but now i'll never know.......just
