Caliper Brackets

[JGC403]

I bought these thinking they were for an A-body. But the spacing in between the mounting bolt holes are to big for the A-body. The spacing in between the bolt holes, center to center is 3.75" and to the top of the arch is 3.125". The cast in number on them is: 990 95020A WN10. Anyone know what these are for?

Looks like 3-1/2 to me

Its 3.75", I just checked again. Its off in the picture for some reason. Pictures were to illustrate what I measured.

That style of caliper mounting didn't start until 74 I believe. As for the spacing...no idea what it would be for.
