i got a 76 280z 2+2, not much rust that ive seen so far except the rocker panels and a little on the rear panel before the rear wheel. i've checked MSA and VB but neither of them sell panels for the 2+2. i found a body shop that will cut it out and form new pieces to fit in. they want $2500 to do that and smooth out all the small dings, sand it down to the metal and do a color change to black. but i'd rather get replacement panels so i know they'll be closer to excact. anybody know where i can look or have any other suggestions. also does anyone know the difference in length and wieght for coupe vs. 2+2? i appreciate any help.

You might try asking one of the places that sell used body panels. I don't see a any rocker panels listed here but they list some 2+2 door shells which means they may have access to some rocker panels:
