Steering Column Collar

Anyone know how easy it is to replace the steering column collar on a 72 Chevelle? My car was originally a column shift but has been retro-fitted with the horseshoe on the floor, so the original steering column collar forward of the ignition collar looks a bit out of place with the column shift nub present without the column shift handle there. My car came with a replacement collar when I bought it a couple of months ago that appears to be a reproduction. Does anyone know how hard it is to swap these collars out, how much time it would take, and if this part is a fairly interchangeable part (i.e., is this kind of part fairly universal/interchangeable on most GM A-body cars)? Thanks!
