The two holes that bolt on to the spindle to calipers are smaller then the 04 Mach 1 calipers but holes alight very well only way I could make them fit is by drilling the holes bigger and recomendations

need to know specifics:
What year spindles ?
The 04 Mach 1 calipers will bolt onto any 94-04 spindle.
If you can post/forward any pictures of the spindles, and also calipers with brackets I can help diagnose your problem.

It's a sN 95 spindle everything lines up koo but the bolt that goes on the caliper braket has big tread not fine and they looks like the problem I was thinking of drilling the hole bigger on the spindle to make the bolt slide it and tread on the caliper. Bracket
Here's the sN95 spindle with single piston caliper bolts righ up
That's a pic of the sn95 spindle with sn95 bolts it barely grabs treat on Mach 1 calipers and Mach 1 bolts won't fit the sn95 spindle
And herers front pic of the calipers just mocked up cuz sn95 bolts barely hold it won't tread

first problem I see is you need to add some spacers ASAFP to your balljoint and use a CASTLE NUT and a cotter pin through the hole in the balljoint, or you run the risk of that non-locking shitty hardware store nut backing off and your spindle/wheel flopping up and dragging the front of the car along the freeway...

a stock castle nut will not make up how much room is there, 4cyl and v8 foxbody balljoints are the same, the control arms are the same. an SN95 balljoint is much shorter. You just need a few washers stacked up above the spindle and below the castle nut to take up the room, 3-4 should do it.
The mach1/cobra calipers use different bolts than v6/gt sn95 calipers unfortunately, you need to get the right sized bolts. I'd suggest taking the calipers and v6/gt bolts into a hardware store to find the right size, which match the length of the v6/gt bolts.

front caliper to spindle mounting bolts are actually the same from 94-04 V6/V8 and the 13" setups.(rear caliper mounting bolts are slightly shorter).
Send me a better picture of the caliper if you can (less glare)
I think I see your problem..... just want to see a clearer picture to confirm

Those are GM 1LE calipers
I guess you "could" drill in order to fit these calipers.
With the "Ford" rotors the caliper will bolt up and NOT rub on the rotor ?

Nothing I had mine like that for a few months. I was a bitch to bleed the air bubbles stay in the line hence why the bleeder needs to be facing up.
