I am running a 235 six cylinder in it which is probably heavy,it has the original springs that have 9 leaves in them and it has the old door closer type shocks on it. Could I get by with taking halve the leaves out of would it be better getting newer springs,heres my plan so far dropped axle,momo leaf springs if taking leaves out wont work,new kingpins, spring bushings and of course modern brakes,tube shocks,newer steering box. I am not planning cross country trips with this truck as it has no leg room but I want to get it better than what it is now. Jeff
