I'm having a new trunk floor,rear valance with end caps, and quarter skins installed on my 68'Charger. I'll also need a rear crossmember and inner wheelhouses as you can see. Does the shock mount crossmember normally get replaced,and are there any other braces of pieces I'd need for this job? Thanks for any info

Rear shock mount brace is not normally replaced unless it's rusted. Don't forget about the fuel tank brace, chances are it may be rusted enough to require replacement. Also a good time to really inspect the rear frame rails and rear spring hangers. I would also paint the inside of the frame rails with some good rust prevention paint while the floor is out.

good advise on coating the inside of the frame rails. i cleaned mine real good and coated with a good rustoleum.
