First post and I'm already looking for assistance.
I have a DB that belonged to my Grandfather. I'm not sure of the exact model because it is missing the tag and had no engine. It is a 2 piece frame with the clicker hubs on it. No bells or whistles.
Although it does have some sentimental value since it belonged to my Grandfather, I don't own any tools that do not get used. So I'm currently getting it into good mechanical condition to cultivate the garden.
I purchased a mostly complete speed changer for it. I say mostly because it was missing the Pivot Bracket and Pin (Part Number 575PA676). It is the bracket the bell crank attaches to. This should be pretty easy for me to fabricate, if I had dimensions for the location of the holes and pivot pin.
Please see my feeble attempt at a drawing of the plate. I need the length of "A" "B" & "C" (Actually just B&C since I already know the centers of the bolts). The filled circle would be the pin location with the open circles being the mounting holes.
