ok i just did the 63 chevy swap and my truck wasn't flexing in the rear like a thought it should so i figured out that my 12 in of travel on my shocks aren't enough i'm going to 14 inches of travel what is the best brand of shock for rockrawlin i'm trying to keep it about 70 dollars for the pair, also i'm looking at some bilstein 5215 series gas shocks what do you guys think, what do you guys run. keep in mind $70
