thanks for the replies - I hit both links noted in the replies before I started on this mod on my car...the problem is the there is no real discussion on the hinge shape itself - only the placement of the pockets, which is very unique on this car - where the S10 door jamb is nearly vertical - I have to work around the angle and the thickness of the jamb itself...
I set the quarter panel back on loosely (they bolt on on this car

) and took this picture to better illustrate the difference between the S10 door jamb vs. the Hudson door jamb.
Where I might be able to use a similar shaped hinge in the top pocket as illustrated in the s10 implementation - the lower hinge is going to have to be a different shape, perhaps even a dual swing hinge to be able to clear the mid-belt line and distance between the hinge and outer skin.
