Calipers

See http://www.svo73mm.cjb.net/ for brake upgrades that won't kill your wallet.

The 73 MM calipers came on several different Fords. You can get them locally for much less money and not pay shipping. Ask for calipers from a 91 Lincoln Mark 7. They are about $20-$25 each, with no shipping charges. You will also need to upgrade your master cylinder to get the calipers to work correctly. Again, see http://www.svo73mm.cjb.net/ for more help.
 
Dang they want a core back... maybe i can fool them by giving them my old brake calipers hehe...

That's what I did. To the rebuilders, a core is a core. The parts guy looked in the box to make sure it was a brake caliper and not a bunch of rocks in a bag and was happy.
