I've posted about it on here several times. Three years ago I replaced the clutch in my Feather Duster. It had 288 thousand (and some change) miles on it at the time. It is completely original down to the OSAC valve. Original carburetor (special to the model), distributor (curved specifically for this model), original 7.5" 2.9 ratio rear axle, original everything. Taking it on a trip and checking the fuel mileage closely over several tanks of fuel following the clutch replacement, it averaged 31.4 miles per gallon. In city back and forth to work mileage (just under five miles each way) everyday, it still gets 19 to 21 MPG, and that is after I replaced the 14" ralleys and 215R75s with 15 X 7 cop car wheels carrying 235/60 TAs two years ago. It is just about to roll over 300K. Somewhere rolling around in a shoe box in my home office I probably still have the fuel receipts for the trip with the odometer readings and fuel mileage computed on them.
