Hot Rods Diamond Point Front Spring

I have a new Chassis Engineering Front Spring on the way to replace the exsisting spring in my 32 Roadster.

I would like to Diamond Point the ends similar to an original.

Would anyone have the dimensions of the end of the leaf and how far up the side the leaf I should cut it.

 

I read on here or Fordbarn that they were not perfect from the factory.I've got an old 32 spring pack and all the ends are square.Its recommended to bevel the underside so the leaf above doesn't wear into the one below.

 

Not meaning to high jack but any one know what this spring could be from? Leaf ends are really thinned..36-3/4" eye to eye and 8" arch..10 leaf..
