Here is the pickup assembly for modern wheelsets:
Do NOT use the 482-3 baseplate and roller with modern wheelsets. This baseplate was designed for the older post-war trucks with separate wheels that freewheeled on the axle. The modern fast-angle wheelsets have wheels that are pressed onto a spline on the axle, and thus turn as one unit. The baseplate in question has tabs that need to be bent over the axles for assembly, and would lock up the newer wheelsets.
