Here is a pic of the front mounts for the G and F series gearboxes, the F is on the right and the G on the left, the only problem I have found with trying to fit the G series mount in the G series gearbox is that the bolts on the bottom dont match up with the frame on my F series car. Tho the metal frames are different aswell it looks like the F series mount will fit in the G series frame, I will find out tomorrow and let you guys know
