Hey girlz55 - this is a typical GEN2 Camaro steering shaft setup (see photo) that you should be able to get away with any column. For the 55-59 truck I think you have to try and find the shortest column available which is about 26-28"????. It uses a joint at the column end and gets rid of the rag joint on the box and replaces it with another flex joint. You dont need a center support on this type.
