Just got one for the Dart from rockauto.com . Price was cheaper than what was around town plus I had a discount code that knocked another 5 percent off the total. Got the radiator, upper and lower hoses and the rear spring bushes at the same time. Cost came in, even with shipping, at what I would have paid for the radiator itself with tax in town.
Don't know how others feel about rockauto, but I've had good luck with them.
If you end up going that route I think I have another discount code they sent me that may still be good. I'd have to find it for you. Alternatively I think I did post it on the board as well with a copy of their emailed instructions to use it.
Hope that helps.
Cheers
