Hey guys my 4 speed gear box has decided to be stuck in 4th gear (i think).
It seems pretty far gone so the questions i have are:

1. does anyone in Perth have a 4 speed for a 120 engine they are willing to sell?
   
2. has anyone rebuilt one of these and if so would it be a worth while option?
   
3. Will a 5 speed bolt up to the 120 block?
   

Thanks for the help

I have a 4 speed box at my place.
$50 for a good 4 speed is good for me.
Ill even take you old box. I really only want the front half of the case thou.
