What brake caliper BRACKET is this?

[Bihili]

This is on my project 2 car.
It came on the car and former owner is dead.

The pictures show a 78-86 GM caliper on this bracket.
It does not fit.
The bracket also faces forward and the spacing between caliper bolt holes is seven inches.
I do not know anything about this bracket.

Do you know what it is?

It's for the bigger D52 caliper - 69-72 Chevelle, etc. As are your rotors.

Lots of suppliers make one.

As always, Thanks Rick
