OK Jeff I will have to do a bit of checking, I have a full crank one here and also one with a Briggs still on it. The Briggs still uses a sliding plate so I need to check if you can fit that plate will work on the full crank chassis, might be a day or so before I can get to it. The pulley off the FC will fit straight onto the PT, but I'm not sure how the belt adjuster will work on them, the Briggs I have pulled off haven't had them so I guess they used the screwdriver method. I haven't tried the other needles yet, I still have a few of the original purchase left maybe 6/7 been busy with other stuff of late.
