p/s box removal

Having trouble removing the p/s box in my 72 dart. It is a 318 with hooker competition headers. The headers are off the heads but will not give me good access to remove the box. The exhaust system is welded from the headers all the way back. I have the box out of the place it is bolted to but can not clear the header. Any one have ideas? If I massage the inner fender it will probably come out. Thanks for ANY ideas??
Loosen the engine and Jack it up a couple inches.
Worse case scenario you may have to cut the exhaust loose from the header so you can move the header out of the way! That side the centerlink goes thru the header so you wont be about to take it out completely.
