RCBS RS3 press--"Ram Priming Unit"?

I am hoping to get my RCBS RS3 set up for reloading .38spl. I just got the dies in, and already have the press.

The thing I'm lacking is a #6 shell holder, and also, a priming ram. Can someone who uses this old press tell me if the RCBS "ram priming unit" works with the RS3?

I'm hoping to use the press, and not have to get an additional tool to seat primers. Or worse yet, have to go back to priming with my Lee loader.

Thanks for any info.

Oh, fantastic. I was trying to read the RCBS online instructions, but the PDF was so pixelated I could barely read it at all. I was hoping they would just have a spec sheet for the priming system.
