thanks I'll give it a try that way first.
So I've been doing my own research, just gonna put my rambling thoughts out there.
It seems the Espo springs are or were just Moog springs at one point?
The Espo part #s listed in the eaglepedia and over on the amc forum are Moog part #s:
http://www.fme-cat.com/PartDetailWindow.aspx?brand=MC&pt=Coil%20Spring%20Set&PartNumber=3156#.UTrECXG7IcsAnd # 3156 is for the Concord Wagon w/ 4.2L and A/C.
I don't think Moog would list a part with a vehicle just because it's close enough, but I also notice they don't cross list it with the Eagle. Not sure what to think there. Tomorrow when I get a chance I'll measure the uninstalled spring to see if it matches the dimensions listed.
However I see now they are indeed 2" too big as the unladen install height should be 9.5" (I measured again properly and my parts car matched) compared to the 11.5" with the Espo springs.
I'd really like to have a new set of springs to go with my new everything else so I'll keep them for now.
Looking forward if I experience the same height issues and it's more than I like, it seems I'm at least lucky it's a straight rate spring with a tangential end. So it can be cut safely if done properly. Anyone ever try this? It'll probably be my likely path unless the spring rate is too much.
