Have 340 swinger and 71 scamp... Do i cut up scamp 4 dart? Or build 340 scamp clone?

i have a 70 dart 340 that needs quarter work, some floor work, trunk, and alot of surface rust.
i just picked up today, a almost rust free 71 scamp. it is a /6 car, but is rock solid inside and out. even the carpet is nice.

my dilema is, i like that the 340 car has fender tag and buils sheet, and i still have the engine/trans. but it needs gobs of work.
now on the other hand. the scamp needs minumum body work. most is under the vynal top. other that a small half dollar hole in passenger side lower quarter, there is not rust in this car. even the floors do not have any surface rust at all.

i love the darts and i lovet the dusters.
should i build the dart up, using the scamp for all the metal, and i would like to put the scamp frontend on the dart, as i like the front ends more.......................
i know it would not be worth as much with the scamp front end on it, but i like the look
help , help

oh, btw, did the scamp /6 come with dual rally mirrors?
