ford gpa g504

Hello,

I'm still looking for the correct screws... this is the closest I can find to my original however it is in Stainless. Could somebody tell me if McMaster Carr part number 91793A540 will work? It seems just a little bit off. The following dimensions come close to matching one of my original ones

Thread Lenght 3/4"

Inch Thread Size
1/4"-20 (I believe 20 to be correct)

Head Style
Binding

Drive Style
Slotted

Thread Length
Fully Threaded

The following does not match

Head Diameter .525"... my original appears to be .50"
Head Height .165".... my original appears to be .20"


Can anybody give me some advice? Is there a better match?

McMaster Carr dimensions


Originals




Thanks,
Tony
