I think that this sounds like sound advice. It is not wise to go willy-nilly into something like this. The car will only be original once, and I wouldn't want you to regret your actions down the road. Joe Savard, Lake Orion, Michigan In a message dated 7/23/2010 12:48:12 P.M.

It is a good idea to replace weather stripping and the wiring harness. It is not necessary or appropriate to switch to a 12-V system. I believe that all C-300's should remain s close to bone-stock as possible due to their rarity. The car can be made to start and run just fine on a 6-Volt system. I have added an electric fuel pump underneath by the tank. It is operated only to prime the carbs and via a push button. This has solved the occasional hard starting problem associated with mysterious disappearance of fuel and is easily removed for any ultimate concours judging. I added simple, old-fashioned black seat belts and our judging does not deduct points for these so long as they are period correct. Many switch to radial tires-P225/P235/15's are available with 3" WSW from several vendors and are an easily-reversed retrofit. I find driving on an old set of L78-15 bias ply Remingtons to be satisfactory, but you have to stay awake and drive the car as it tends to want to drive itself from time to time. You may experience poor performance of your power brake system. These have a large internal diaphragm that can leak or rupture. Various vendors can rebuild these. That's why these cars have 9" wide brake pedals-for both feet! I'd forget about a/c for a C-300. Several came so equipped from the factory and every other '55 Chrysler sedan or coupe could be so equipped with the rear-mounted unit. Having lived in Houston five years, I do understand that a/c makes life more enjoyable, so if you do add a/c, try to make it a reversible modification. I'd suggest you ponder these issues, move forward with the wiring, cosmetic and mechanical maintenance and not move on to the 12-Volt conversion or addition of /c until you have developed and refined your own philosophy for being a great steward of this rare old brute. It's your car and your call. Thank for inviting comment and support. These clubs are good at that.

My car is mostly restored, needing only chrome work and weatherstripping around the doors and windows to be cosmetically close to perfect. Before that happens, though, I would like feedback on my intended first project: having the entire wiring harness replaced, conversion to a 12-volt system, and having "Vintage Air" a/c installed. Since the power steering pump is mounted on the rear of the generator, would it make more sense to simply have the stock generator converted to a 12-volt generator, or have an alternator mounted and install an electric power steering pump? How about changimg the pulley and mounting an alternator that operates in conjunction with the generator? Do my power window motors and seat motors need to be replaced (like my potential installer has told me), or can resistors be installed so they will adapt? Any advice or opinions would be most welcome. Thanks!
