LMC vent assembly fitment issue?

[vikingsandpintos]

I am changing the window regulators in my daughters 67 C10. The vent windows were pretty rough, so while they are all apart I ordered new assemblies from LMC. This is just a daily driver quality truck, not a show truck, but still want it looking decent. She wants to have it going for a small local car show next week so trying to hurry and finish enough to make it take-able! lol

Put the driver side in last night. All the screw holes line up, but it seems to sit a little low. There is a small gap at the very top, enough to see light thru. It looks like it needs to be a little taller, or move up some, but there just isn't any adjustment to slide it up. Does this look right? Can I just put some clear RTV to seal it, or is it just not correct? Also, at the bottom, the seal doesn't quite touch the outer door where the big window trim is. Do I have that all correct, or does the long door piece need to be trimmed? I think the PO put that trim on it, not sure if it is original or not, but looks long to me. But, I'm new to these trucks and have nothing to compare to previously.

As a side note, what is the best way to lube the slides, to keep the new regulator happy? Just white lithium or WD40 sprayed in there good, or something else? Thanks!
