thanks all for your comments
think I will look for nos pass quarter (AMD last choice)
need work on wheelhoust + extension (both sides)
I want /need my dart done >> parked it in 1985 in garage
The bad news I can't weld anymore (defib installed 2011)
I can remove qtrs fit and attach qtrs on (hire welder to spot weld)

I realy dont care about value (although i would think twice if i was looking @ a car with extensive patching warping bondo etc)
I would think very hard about buying

So oem/nos quarter panels and AMD wheelhoust + extension
is the way I'll go
I don't know if this is such a RARE dart see lots @ carlisle

70 dart swinger 340 4sp 3.91 posi #'s match plum crazy, white vinyl top
thanks
