Gene, With the pivot blocks installed on the tray outside of the action cavity, draw a line on the tray that connects the back of each pivot block. Remove this material and recheck that the tray does not rub against the bellyrail as the tray rotates. I cut the excess material off on my tablesaw using a taper jig but you can also use any number of other methods, bandsaw, power plane etc. This is quite common also with the Stwy O.

It appears that the options are to either plane off the back side of the new tray or trim the tray at the opposite end where the lift levers rest. The original tray was trimmed under the lift levers so it was wider at the bass than the treble. As the Renner kit is made of pin block type material it is probably not an issue to remove 8 to 10mm of stock from the back of the tray without weakening it so this appears to be the option of choice. Trimming the tray under the lift levers at the opposite end would seem to make regulation difficult. Curious what any of you do when you encounter this sort of thing.
