If the core support bushings are new, or not, you can put a couple more fender washers under them. I put two washers under both sides on my 91 OCC, because the cladding was catching the fender. The washers will lift the front of the fender, but you must loosen all of the bolts on the fenders, and where the wheelhouse bolts to the firewall brackets, except the one at the top door hinge (so it rotates on it, as a pivot), and at the core support. The wheelhouse will move with the fender. You must adjust the front bumper to match. If the bolts are a little short when you raise the core support, you can get longer bolts. The fender/door gap will move about half of the height of the core support increase. It should not affect your hood alignment, because the core support aligns the hood, and you are not changing their relationship. Just make sure the core support is the same height from the frame on both sides. You may find that you need an eighth inch shim between the wheelhouse to firewall mounting brackets.
