It will move left and right at the door, but it will not budge up and down or for and aft on the front end.
Did you remove the interior door panel to gain access to the 6 bolts on that end of the hinges?
Also, I think, no I KNOW my car was in more than one accident. I had to play with the body mounts quite a bit at some places to get the lines good, well not good, but a lot better than they were. There is a guide somewhere on that.
Fuzzy it is a 56, and unlike the 55 and 57's the last 2 suggestions you make are not going to work very well. 56 fender adjustment up (at the rear) may not be able to be done because the lower bolt goes straight up in the brace on the end of the rocker. If that brace is installed wrong, there will be no up or down movement.
Looking at the photos it appears to me the lower mount needs to have washers placed between the rocker mount and the fender to stretch it and flatten the curve. It also must be moved forward.
The front hood to fender is another matter all together because the grill top bar has no holes in it to mount to the inner fender/fender. The adjustment is made using a special "L" bracket to move the fender out. It is a very poor excuse of a bracket and most 56's have an issue on both sides as a result. You almost have to shim the grill to turn signal backing plate to make any significant adjustment there. Add to that the reproduction hood bar is flatter across the front and this tends to make the front of the hood wider as a result.
I'm having that same issue (front hood/fender gap) after coming out of paint last year. Thank you for the tip!. I struggled to get a 1/8" gap.
