Help 6 speed box fitting problems bad times

:dontknow: I have just started fitting my 20vt plus 6 speed box to my mk1 cab and have hit the usual problems already I stupidly wanted to use the mounts out of the donor seat leon cupra, so today I removed my old drivers side engine mount and slotted engine and box, I've seen some picks of some one using original mounts in Germany and I want to follow suite   But now I wish i just bought the mount also drive shafts are to small where they bolt to gearbox what combination do I use any one know? Picks to follow
