I have a '78 GMC Shortbed 4X4.  I bought the truck partially completed on a frame-off restoration, and while the guy already replaced the rear springs, I still need fronts.  Currently, the rear has 2" lift springs and I'd like to do the same on the front.  I'm looking for advice on 2" lifted front springs with a mellow ride.  Any advice/ part numbers will be greatly appreciated.
