Maybe you just need new springs. That would be a cheaper try at fixing the problem and you would have to go thru the pain of hinge re-alignment.

There is a pretty good picture of them installed.http://cgi.ebay.com/ebaymotors/Billet-Hood-Hinge-Mustang-Shelby-Eleanor-1967-1968_W0QQcmdZViewItemQQhashZitem33583c2b2cQQitemZ220523670316QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
Wore out the bushing? I hate to ask but are you sure they were adjusted properly?
