Lets not talk about Michigan's winter, oldest daughter was smart enough to skip town down to Georgia, thats been a popular spot for visits this year. I'm just south of Metro Airport SMC, where you located?
I agree with Matthew, for what the stage two kit costs, you can do whole new Stock suspension with the judge sway bars fore and aft, front and rear Disc brakes and premium gas shocks. Add in a set of Drag bags for your rear springs to help with roll and traction and maybe some adjustable upper and lower control arms and still have some change in your pocket.
I think my Tempest rides better than most of the "new" cars i have had. Lets remember it's a 2 ton full frame coupe that's probably got 18" more wheel base than your new car. It's was meant to be a boulevard cruiser and does quite well at that, with the right tweaks it can be thrown into some corners with limits. These cars were always a little traction deficient mainly do to the torque our motors make down low.
I think the 71-72's are the most muscular looking of the line, love the "in your face" hood, lets see some pics.
