So here's where I am at today. Morryde sent me replacement hinges thinking it's an issue with my hinges. I installed them and found that with the new hinges I still open close to 7 degrees past 90 degrees and the stay arm still pops out. The difference between my hinges and the new hinges is that the new hinges have some plastic "bumper" piece on the corner that limits travel a bit. Unfortunately in my case it was still not enough and I had to glue in additional piece of hard plastic into the limiter that's added to the hinge (when I have some time I'll take some detailed pictures).
So this is my summary:
1. Hinges by themselves are great. I had no issues when I was running just the hinges.
2. When I added the Morryde reinforcement brace to the tailgate, the reinforcement did/caused the following (and I haven't had a chance to address everything)
- The thick spacer that goes on the body side is too thick in my case. I can see clearly that the gate isn't sitting flush with the body - spacer is just a hair under 3/32" too thick.
- The thick spacer shifts the stay arm position. The shift in position I believe is what is making it pop out earlier in my case - had to address it with an additional limiter to make sure that the hinge does not travel even a hair over 90 degrees. Btw, in the JK the expected opening is just over 90degree to allow for the gate to fully clear the opening in order to have access to the full width for loading. This is a deficiency on the Morryde design and while it can be worked around, there should be a warning for people to be aware of potential issues.
- As I mentioned above the spacer shifts the stay arm position which affects the arc of travel and in my case it makes it interfere with a body seam inside of the body (had to remove the tail light to see it). If the spacer was even 1/8" thinner I would have cleared the lip inside of the body. I had to grind the sheet metal inside and then paint it to secure against rust. I removed just under an eight of an inch and there is no more interference. Again - deficiency on the design as it did not take into account the change in the geometry of the position of the stay rod and the way it travels. Granted - seems folks haven't complained about it, and I probably would have ignored the additional "pop" noise from opening and closing the gate if I didn't have the issues with the stay rod popping out. I can see how the stay rod could "self correct" the sheet metal interference issue as with time it would wear out (in my case it already bent out slightly) With more opening/close action, I could see it bending it as well as shaving some of the surface of the stay rod (it's coated making it "thicker) to the point that it would clear without interference (again - not how this should be addressed).
I will state this - Kudos to the Morryde folks for working with me towards resolution and many thanks for providing replacement hinges. Thumbs down for not listening to what the actual problem is. I explained the interference of the stay rod, misalignment of the gate position in relation to the body and how the geometry changed and it was ignored. My issue I believe should have been addressed with thinner spacers (I didn't want to butcher mine for experiment purposes, didn't have time to make new ones from scratch with the appropriate shape/thickness and hole placement and spacers would have been cheaper to send out then hinges). At the end when I provided the detailed report to folks at Morryde, the response was that they're glad that the new parts provided improvement for me. Frankly, the parts did not really do much - I had to glue in limiters and grind the seam inside of the body. I believe that addition of the gate reinforcement could (again, not all jeeps were created equal) cause issues for other folks as there impact of the shift of the pivot point away from the body of the jeep through addition of the spacer has a domino effect on other parts.
Anyways, if someone asks me, I will say, buy the hinges, with the gate reinforcement though buyer beware - it might require modifications outside of what you were expecting from a bolt on install.
