after driing the car load and giving it abuse at every chance i have broken the gearbox mounts(polly bush with bolt through centre) 1st to go was the front(pulled the bolt in half) then the rear went the other day(same thing hapened to the bolt)and when it went the inlet hit the bonnet and dented it(lucky paintless dent removal can get it out) and the waterpump hit the inner chassie leg(there is normaly a inch and half gap between the two)

what type of gearbox mount is every one using on there big powered rst's and frst's, any help would be good as i dont want to brake any more
