I recently acquired a fibreglass 308 GTB - its had quite a hard life and seems to have weak synchros on 2nd, 4th and 5 th gears. The local agent seems to think it could be the clutch that's dragging as the shift quality improves dramatically when shifting at higher revs. Any ideas out there? Is there any way to test this without stripping the 'box? What sort of mileage is reasonable to expect from a 308 'box before it has to be torn down?
