Thanks Greg,
I inspected the inside very closely after I talked with you and I'm pretty sure the cab corner is solid, not so much on the pass. side. That's exactly what I did on the pass. side rocker to check alignments but I was also using the stock rocker so I new it should fit. This repop seems to be a little off on either length or the curve up to one of the door pillars. I'm still working on it.
I'll do some more research and fitting on my next days off. I've spent a lot of time looking over Alan's build for info, also. His build has been a great resource.
