I'll try the LMC guys, a 2" drop would be perfect. If I understand Carl right, the 68-69 ( what about 67? ) springs are shorter than 70 - 72. By how much? That could be a nice solution. I don't have them all lined up here to measure. It's those damn little details that mess a guy up everytime. I need to go down to a boneyard and spend some time measuring stuff.
Carl, what makes the front end push that you mentioned, too stiff spring or not enough?
