We finished restoring our 68-C last year, and wound up having to re-do everything. When we started I was hopeful that we might be able to avoid having to replace all of the wood, but almost ninety years had taken its toll at the rear of the floor sills. We purchased this car from the son of a fellow (who died in 1995 and) who purchased it used in 1936, so it was pretty much complete. To hopefully give you some comfort with the price, I'm thinking that our initial acquisition costs was roughly $12K.
If I can help in any way (from here) with photos, etc., please let me now. I've never been able to send photos on this site, but if you might provide me with an e-mail address, I'll be glad to provide you with photos throughout. We did take a few liberties though in re-doing this car - stained and clear coated new wood, sound deadener on all interior panels and extra heavy felt under the carpet on the floors, heated seats, turn signals, and a trunk hitch for our matching Mullins trailer. I will say that this is the quietest of any of our Model A's. Please feel free to reach out if there might be questions that I can help you with. Good luck to you going forward.
