A local old-time muffler shop (Antioch Muffler Service) also has these cards, at least back to our '55 C300. The cards control the bending of the various pipes by an automated pipe bender. I believe the experience of the old-timer probably resulted in a few last minute adjustments to assure a rattle-free installation. I let him talk me into combining the original two pieces of the exhaust pipes from the manifolds to the mufflers into single piece-and also to ignore the intermediate clamp that stabilizes these pieces to steel ears projecting from the PowerFlite pan area. As I recall, every additional joint allowed the installer some additional flexibility in adjusting the pipes for maximum clearance without heating and beating them. If I ever redo one of these exhaust system, I'll insist on factory-original configuration-even if it is somewhat inefficient and more expensive. I'd also try to find a complete set of original-type clamps and hangers and insist on their use. I had them use aluminized, rather than stainless steel piping and the pipes still look good. In spite of demerits, I do like rumble and song the three-chamber Flowmaster mufflers allow.

The local muffler shop in Fort Dodge makes systems for any car from the make-up cards for his bender machine that he has saved thru the years. When I took my 64 K in, he found the appropriate template card, made the pipes and I was on my way. The owner was sort of a car enthusiast himself, and the price was the same as would be charged for any vehicle system right up to present day. The advantage was that I watched the process while it was being done, and it was basically a custom fit at the same time and all I had to do was watch. I did add the chrome tips at the end which may be non-standard, but really looks kind of neat. In the end the whole thing was far superior than I could do at home in my own shop. Just something to consider. 300'ly, John Holst... ---------- No virus found in this outgoing message.
