i recently bought a 68 gmc it has everything even an old aftermarket a/c which does not work. does anybody know anything about these. did anybody take them over they look alot like other after market a/c. mine dosnt work cause its missin the a/c pump. Also the hoses that were conected to the pump were left to the air, so the systim has not been sealed for a while.. the fuses have not been hooked up either.. can it be fixed. i thought i would fill the lines with break cleaner and blow them out with compressed air.. any help would be greatly appreciated. thanks andrew
