So are you going with original exhaust over reproduction ? Fred has that too I bet. How about the battery cables ,plug wires, belts ,hoses? All original or reproduction ? What about the Holley original assemblyline or re issue? Just for a example the concours repro end link kits AMK sells are exact except they don't have the makers mark on the bolt heads and the makers marking on the spacer tube that you can see if you look close . The AMK kit is 25.00 and the NOS assemblyline kits sell for 200.00+ many times. This kind of spread is typical for many assemblyline parts compared to the good repro parts. Sometime less sometimes more . Since you are un familiar with the parts given your questions I thought I would bring this up in light of your "as original as possible to the K-code it was when it rolled off the assembly line 23 Oct 1965" statement just in case you are in aware. Trying to help you understand so that you can choose the best path.
I haven't decided on which exhaust yet but it will certainly be with an h-pipe, so something very similar to stock on my kar. I will turn the tips down and cut off just flush with the bottom of the rear valance. Yes, Fred does have what I need too.
I do have a set of AMK end links. I ordered them from NPD. I'll probably just use these instead.
My kar has a Holley but not the original one that came on shelby gt350s unfortunately.
Yes I will probably be buying new belts, hoses, battery cables. I already bought new wiring harness and engine bay harnesses.
I do love how active you, Jeff, Bob, Carlite, and Caspian are on this website. I'm learning a massive amount about my kar!
