F150 Knuckle casting Numbers

[cbfomoco]

I am looking for the casting numbers for the left and right 78-79 f150 and bronco steering knuckle. I am working on going back together with mine and just want to go with the 78-79 knuckle's so it will clear the 15 in wheels I already have instead of the 76-77 bronco knuckles that I have. One junk yard I was talking too need casting numbers to verify any help would be great. Thanks
