Well after some messing about with the bolts i fitted the new diff mount i got from msd, took the car out after just to make sure it was all ok
From getting in the car it felt higher at the back and alot more SOLID, got a few miles down the road and i must say its makes such i differnce to the feel of the whole car . A must have /fit for £120
Next up is to get some new springs ,as mine look like they have sat on the bottom of a river for 26 years and why i was under the car i noticed my rear anti roll bar bushes are falling apart so i will get both items during the week ready for next weekend.
But all in all im happy
