TFU! Sorry for your lose. My disc conversion cost around this much w/ out labor. Loaded 91 Mark VII 73mm front calipers $85. Loaded rear 88 T bird calipers $135, Rear rotors $70, Northracecars conversion brackets w/ ebrake cables $220, Classic Tubing SS lines $160, Cobra or 94-95 Master cylinder and booster $225, Ford Racing (plug to gut distribution block) $20, Brake fluid $10, parts cleaner $5, rear diff gasket $5, gear oil $15. There are a few things that can be substituted to make this a little cheaper like no or half ss lines on front only, stock front calipers, a t block instead of the plug, use stock booster, no parts cleaner, etc. This can range from $500-$1400. I would say it takes about 6 hrs to do the swap. So anything under $500 would be good, but get it in writing first! This job has some fabing and minor machining, that they will run into unsuspectedly. Like your rear housing will most likely need to be filed for brackets. The e brake handle/mechanism has to be riveted together to work correctly. Calipers/rotors will need to be shimmed, and brakes will need to be bled.
