Newbie in MI w/ 1969 340 Swinger

Yeah, I'm actually from Vicksburg, just a little SE of Kalamazoo. I've owned the car since 2000 and as far as I know it has the stock springs, but it has air shocks on the back that are pumped all the way up in the picture. Figured I'd throw in a couple pictures of my first car 1972 Challenger I bought in 97 when I was 16, and my dad's 70 Cuda he has owned since 1973. All 340 cars. Great site guys.
