[T3] Late Model (dual bleeder) Caliper Assembly Bolt Question

[Tim]

I have 2 Calipers.  One uses socket cap screws.  The other uses hex head
bolts.  Both are 7mm x 1.0mm pitch.   Both are 12.9 strength spec.

Any insights on when the changeover was made?

Any insights on where to purchase new bolts/screws? (at a reasonable cost.)
