Finally installing the 8 3/4 in Bluefish

Whats the possibility of exchanging the springs for taller ones? My new springs settled about 1/2" over the next year. I know its a lot of hard work but when are you going to change them again?
Not sure yet on the springs. I'm used to the back end up in the air with air shocks. Once I get the driveshaft in I can get the car outside and get a real good look at it. It measures close to level, guess I was hoping for more.
Good news is I picked up the driveshaft today and it measures exactly what I think it should be. Sunday I"ll see if it fits. Larry
