New Door Shell does not fit???

[Kisner]

Welcome to the world of reproduction parts. Can't tell you how many I sent back or at least had to hand massage a little to get a good fit. Sounds like it's a warped door shell. I'd send it back and try another. With that much off, you won't be able to align it properly by adjusting the hinges. Had the exact same problem with my 68 trunk lid. Returned 2, but the 3rd one I kept still doesn't fit properly. After I got it as close as I could by adjusting the hinges, I ended up setting 2 concrete blocks on top of one corner for a week and it did manage to get it closer. Would've used an original one but couldn't find one that wasn't rusted out towards the back lip.
