hey guys. is a coupe box a 56A? i blew up the gearbox in the yellow ute the other day(56A). so i went to a mate and he said he had a box i could use. he said it was out of a coupe. its got no markings on it. so i installed it. just about everything lined up good. but the clutch pedal was REAL tight. and the yoke had no back and forth play in it. it was pushed right up tight to the gearbox.

anyway. i used the the spring, fork and bearing out of the the blown box. it looked in better condition. but it didnt work at all. i could put it in gear and let the clutch out and it wouldnt move forward anywhere. so i pulled the box out today and looked at the spring and it seems alot smaller than the 56a box one? would this have anything to do with it? or should i just suck it up and get new bearing in the other gearbox?

any help would be appreciated. thanks.
