Firstly, I can confirm that the Granada rotors, bearings, and seals fit right onto an early Pinto spindle. No problem there.

I modified a pair of '74+ metric caliper conversion brackets in a similar fashion. Some pictures are in my build thread here:

What I wanted to add is this:
- Modifying the brackets makes them and the calipers fit over a Granada rotor. However, if the car's front is lowered substantially like mine is, the caliper banjo bolts/hose ends will hit the upper control arms and it gets worse as suspension compression increases. It greatly reduces turning radius once contact occurs...like under hard braking.

Addendum to the last paragraph: It looks like there are two versions of the calipers I got; one where the banjo fitting and bleeder are on the top (the style I have) and one where the banjo is on the bottom and the bleeder is on the upper rear. It looks like the latter with the inlet on the bottom and rear bleeder would probably improve clearance with the UCA by a decent amount.

Since I still have to change to the front hoses, I may put my calipers on opposite sides to get that clearance at the expense of having the bleeders point downward...whi ch will require unbolting them for proper bleeding. It's not an uncommon technique used on motorcycles where the MC is substantially higher than the caliper.

Julee:
Thanks for the info Dick. I have purchased a pair of Granada rotors and will be starting the swap soon

Turns out the stainless hoses I have are too short to use with the calipers upside-down, so I had to keep the rubber lines. It was a PITA to bleed them this time, but it got done. The hoses clear the springs better and UCA clearance is improved, but I think some steering limiters will still be necessary until I figure something else out.

Wittsend:
Any possibility that a hole can just be drilled/tapped at the top or is this one of those "metal doesn't look thick enough" things?

65ShelbyClone:
I actually did think about that when flipping the parts around. I was reluctant to because the caliper has a sizable boss cast into it just for the bleeder and I didn't really want to disassemble the whole thing just to see if metal behind the piston was thick enough.  The bleeder seals on a taper at the bottom too, so I'd have to get that right or figure out a way around it. I think that's why the threads are so deep.

This car is pretty nose-heavy and fast with a tinfoil chassis and plans to go faster so I want the brakes 100% reliable with no uncertainties. I may investigate it though. On the other hand I'm really looking hard at some Afco aluminum calipers...
