My 4th gear synchro gear is bad and I double clutch into 4th (instead of coasting). I actually like that because it makes me feel in tune with my '48. If I had to double clutch more than that, it would be a pain in the rear.
My tranny shop said it would cost $200 to fix the 4th gear synchro and $600 to overhaul the whole thing.
