The hinges may be removed from the cowl but it is very difficult with the fenders in place, The easiest way to do the pins and bushings is to remove the doors from the car--apply several layers of 2 inch masking tape to the front edge of the door and also fender to provide some protection, have help on hand to remove and install the doors. Remove the lower hinge bolts first then the lowest of the upper bolts and lastly the very top. Replace the pins and bushings and install the door. Remove the door striker so the door will not be able to latch closed during the adjustment process. First adjust the door for height checking bodyline alignment and a parallel rocker to door gap, then adjust the depth of the door to the fender, rocker and quarter panel, check your glass fit. It the door is low or high in the rear and you ran out of room for adjustment additional can be obtained by moving the cowl side of the hinge-to bring the door up in the rear loosen the top hinge bolts and slide the hinge forward. After the door is aligned properly reinstall the striker and adjust so the latch does not drag on it while closing. This is usually a 1-2 hour job per side for an experienced bodyman. take your time so you don't chip your paint. Hop I helped. Bob
