Thank you both for your prompt replies. I'll see if I cannot get a spring and install it tomorrow. Incidentally, I thought all Eagles were F-heads and didn't think to put it my request.
The response time is amazing. Within a couple of hours there were two views and two replies when I cranked up the computer after supper. I had no idea that the site was so active.
The first new car I ever bought was a a 1954 Aero Eagle. It was a very satisfying car, although the crankshaft broke at about 40,000 miles. Probably from over-reving. The 1,000 mile check up was by a Willys dealer in rural Pennsylvania as I was driving from Arkansas to New York. The mechanic (I think he was the dealership owner) was a friendly young fellow who told me that he raced Plymouth, Chevy and Ford owners in low gear. His crank hadn't broken, tho. I don't remember hitting low overdrive, but second overdrive was common.
Salt was, and still is, extensively used in Pennsylvania. It attacked and was one reason I gave the car to a friend after 100,000 plus miles. This one will not be abused.
I saw a post which mentioned putting disc brakes on the front. That is something I'd like to learn more about. My brakes were never anything to brag about.
Thanks again. I expect to enjoy the car this summer.
