Im currently in the process of readying my shell for my engine again.
Now i was going to buy new engine mount rubbers' But thought is it worth using a strong bondant to fill in the gaps of the old rubbers. There for making it far strongger and rigid than standard ??

My rear mount will be solid one.gearbox mount dosent need anything changing. and the front mount is already adapted so i dont have to cut or weld owt.

I dont want to be paying out stupid sums of money for these bits.
Has anyone done this? if so what did you use and was it worth it?
