Hi.. answering both Mike and Roger... Mike, I have had a few radios converted from stock AM to high-power AM-FM by Antique Automobile Radio, 700 Tampa Rd., Palm Harbor, FL., 34683. (800) 933-4926, Fax (727) 789-0283. ; very satisfied with their service. I would just add that, in the case of the 1964, an AM-FM radio was available, and if one could be found cheap, working or not, it would make a better candidate for switchover than the stock AM, as it would have the FM dial... Roger, on exhaust systems: Kepich has a terrible reputation - pipes that don't fit, and no effort on behalf of the company to make things right when that happens. I have heard many sad tales to that effect. Unless someone else on this list knows somehting I don't about another source for these pipes, best way to go is to find a good muffler shop, and have the pipes fabricated on the car. My local Meineke has a very good manager, who does the custom work himself, knows how to use a pipe bender, and takes pride in his work. The average cost of a custom exhaust system, identical to stock, from downpipes back on a ram car, or from exhaust manifold back on a regular car, has been $300 - $350 bucks out the door. THis is the way to go, I think.. John
