First time on here and was looking for a little advice.Ive got a 55 2nd series with a 350,350 turbo combo,12 bolt rearend.I did all of the work on it in the early 70s and have never had it on the road.Now the time has come to do a few updates.Im looking to install disc brakes with a firewall mount power booster and possibly monoleafs on the front to bring it down a couple inches.Just wondering how these springs work and also if anyone has had any issues with the firewall mount as opposed to frame mount booster.thanks for any advice.
