450 6way Blade wedge shape/size/profile ?

[Mariner]

Hi everyone,

I was looking at the old blade for my loader (with outside frame)
and thinking it would be great to be able to replace the old wedges - they are all well worn, beat up and the heads almost touching the bars.
Does anyone know where I could get or find a drawing giving the wedge details and angles? I am sure there is an optimum angle that has been used successfully in the past. It would be great to get a set made - they look to be made from 1/2" plate.

Any information would be greatly appreciated.

Thank you
