Abel starter switch return springs
 

Just a heads up about a source for return springs for Abel starter switches. I took an old rusty original switch spring to our local Graingers outlet and the nice counter man measured it and found what appeared to be a very close match in the compression springs that Grainger sells. The only catch was that these springs only came in quantities of 10, which came to $16.10. Stainless steel. I installed one on our 28 business coupe and it fit perfectly. Plenty stiff, but works. The starter rod cover goes over it nicely.
