Caltracs question.

I picked up the springs from a classified site here. They are new and never installed. Not sure on the hight... but going to buy the Caltracs and shackles. My ride is a street thrasher with a solid roller iron headed 340 with 4.88s in the rear

Looks good, is that one of those Canadian 340 twisters. Like big foot and the lochness monster.
