I finished reworking the aft ends of the nacelles. Now have to look at the framing around the bussard collectors and decide if I need to do any rework there (sigh).

Reworking  the aft ends of the nacelles...

So this what I'm shooting for:

This is how rough they looked AFTER cleanup. This will get the same rebuild treatment as the other side...

Scribed plastic sheet will replace the grills on the aft ends of each nacelle. I'll build a new frame around and on top of the new grill sections:

After laying on styrene strips the framing of the port grills is complete. Note that the sides of the nacelles gently slope upward so the grill openings are not straight sided trapezoids either.   I noticed this in  the CGI images:
