I have an RCBS case trimmer, the older model with the T-handle and collet for holding the cases. I want to convert to the new lever handle, so I ordered the conversion. Now that I have it the parts don't seem to fit. Maybe I can't figure it out, it just don't seem right. Anyone else did this conversion? The parts that came in the kit were the handle, the large part that the handle attatches to that holds the plate to hold the case. Two saddles, these are the parts that don't seem to fit. Any help would be appreciated.
