Need help pinpointing what my previous owner did.

ok, i got my car with a 5 lug conversion and 4 wheel disk. the rear rotors appeared to be 11.65 with a rough measurement so i finally got around to buying the stuff. converting to 13" fronts, keeping 11.65" rears. just changing to a slotted/drilled rotor in the rear.

im having them installed today, and the fronts should work after i get my brake lines. now the rears wont work they say. the overall diameter of the rotor is too big, and the offset is too much.

before i had a leaking seal from the same rear calipers, it ended up being an SVO seal kit to fix it. so my question is, what size are svo rear calipers? is there anything that uses like 11.25" rotors in the rear?

i dont exactly want to keep slotted/drilled rotors in the front and plain rotors in the rear. i have no way to contact my previous owner, or any other leads as to what he used. thanks for any idea's..

bump..

got my front 13" brakes on after a bunch of bull****. reguardless now i have the nice slotted/drilled front rotors, and the same plain rotors in the rear.

the rotors i have are just a little smaller then 11.65" so im trying to figure out what uses those size rotors in the rear? roughly 11.25", 5-lug pattern.

according to that, the rear rotors are 11.365 which is about right. for a mark/svo

now i just need some pics of one at multiple angles. thanks for the link

dont happen to have any pics of them laying around do you?

im looking on the brembo site to try getting some dimensions of them, but all they have in the ford section are weird cars. assfires, expeditions, contour, nothing mustang.
