Hi I put a 1977ish Lincoln 9 inch rear end disc brake into my 1967 mustang...I'm now wondering what part do I need so the rear shocks can be placed on. The part that the u bolts bolt to has the wrong angle so I can't attach the shocks to the top of trunk and rear end...need part ## or what type of car..like 1967 ford maverick...something like that...thanks everyone...
