Delco Moraine Brake calipers

[Unreal]

I got my long slot (732, I think) for my 499 distributor that way. I used to check at almost every parts store. (I say almost since I never stopped when my wife was in the car!!) A guy at O'Reiley's asked what I was looking for, and when I told him, he called all the other stores in the area, and asked them to check their stock. When that netted nothing, he ordered 3 distributors for me to check out. None was a 499, but one had the 732 cam. He allowed me to purchase the distributor, exchange the shaft, and return it.
Now that's a friendly parts store!!
