Main Door weatherstrip - ZR-1 specific?

[Fully Vetted]

So, I decided to tackle the weatherstrip project over the weekend and between me, Keen Parts and Corvette-Rubber we are trying to figure out if the main door seal that goes around the bottom of the door is ZR-1 specific. None of the suppliers (including Corvette Rubber) have a ZR-1 specific part number but it is clearly a couple of inches shorter than the one that came off and if I'm not mistaken with the ZR-1 being wider the doors are also a tad bit longer which would make the standard C4 weatherstrip too short. Now, I know that a 20 year old mounted seal is going to be longer than a brand new one but look what happened when I went to attach it:



The end popped right off. And this is the good Latex product. Not the cheap stuff.

The distance between the top of the weatherstrip where you attach it with screws and the first clip is not even close to the same:




I verified with Chris over at Keen that this was the correct part number first and now he is talking to his suppliers about a ZR-1 specific part number but I thought I would post here and see if you guys have had the same issue.
