J-hinge and gasstrut.
The template for the gas strut in the build manual is not correct. I think it`s for a 12" strut (as of Rumbles build log), mine is 15.5" (ball to ball) as delivered with the car. I ended up buying new ones anyway, 13.5" long and I had them filled to 610N, approximatly 140lb.
The door didn`t open as much as I wanted it to, so I modified the J-hinge by drilling and tapping a new hole about 3/4" further up towards the heimjoint and enlarged the hinge opening a bit. I also grinded the bracket some. The limiting factor is now the outer top bolt holding the hinge bracket. This mod should not be done without strengthening the area around the hinge bracket. I made a 3mm SS plate between the FG and the bracket.
The strut clears the chassi and HVAC lines open and closed.
When it comes to the heim joint, the longer you have it the better. I started out in the middle (14 turns-28 total if I remember correct) and from there another 3 turns out, this not only makes the door open more, it also helps clear the front of the door not hitting the top/aft of the clam.
On the 5th picture you can see the marked line where I planned to grind the door for clearance, that`s a whole lot, but 3 turns on the heim joint made this much difference, it now clears the clam without the planned grinding.
