No idea where the market is on these but if you'd sacrifice on the color and were willing to travel, this orig. paint Canadian 4-Spd car caught my eye a week ago..
70,000 Km is about 44,000 Miles..

Whatever you may consider or buy, don't forget GM Canada has the microfilm on file for ALL '77 & up F-cars now and can supply the GM document pkg. regardless of where built or shipped to new..
Good luck!.
