Hello, gents.
I have decided to reproduce the 52-58 lock and light cylinder mounts and retaining clips. (71620-52 and 71621-52) They are about done being stamped as original. The drawings look excellent but I haven't held any parts in my hand yet. I'm having them cad plated with the exception of a smaller number of the retaining clip done in park. I have surmised that they were parkerized early on and switched to cadmium at some point. The NOS clip that sold on eBay a while back was cad. They can't be seen when installed so I'm not going to fixate.
I have found that there are a couple more hard to find brackets that I may reproduce depending upon how this project goes. I am open to suggestions but I have found the following to be difficult to find and not reproduced. The parts that cover more years would get priority.
27448-57 Throttle Control Coil Bracket - 57 up
38676-52 Control Coil Bracket - Frame Mount 52 up
69029-57 Horn Trumpet Mount Bracket 57-64
56628-57 Horn Mount Timer Control Coil Bracket 57-64
I will follow up on the current project.
