some q's on 72 demon 340-3 spd i just picked up

ok, i just picked up a hulk of a 340 3 speed demon. after looking it over, it is not as bad as i thought, so there is a possibility i might re-do the car this winter.
i have the fender tag, title and vin still on car.
here is tag readout
v8x en1
n23 n41 n42 r11 v21 v6x
v1x u g36 j54 m21 m43
fe5 d2x9 tx9 327 486959
e55 d13 lm29 h2b 369858

i am wondering if the v21 option was the demons with the painted grille? or was it JUST the hood part?

c'mon guys, give me your opinion on restoring this or not......... needs a complete roof skin, passenger quarter, center trunkpan, driver fender, all interior, engine/trans and also needs some work to the passenger front rail where it butts to the t-bar crosss-member. driver side floors are nice, but passenger sides need to be replaced. hood is good, trunk-lid id toast. the tail panel may be saveable. not rusted at all.
