Cpp (www.Classicperform.com)sells a conversion kit that has the 5 lug roters and brake calipers and brake hoses along with the adpts for the bearing on your axles to convert from ball to roller. That is what you will need if your going with radial tires to help keep your truck in the road.This is what i used on my '48 along with gas shocks and hangers
Good luck!
