I've replaced the "Z" plate of the PR2 scraper baffle with the reworked version. This went very smoothly and I was able to do it without removing the assembly from the chamber. The new installation cookie cutter looks like it will work well and not interfere with any dog clamps however there is a table mass in the way of the correct baffle position. This mass seems to be in a different place than the one at LLO that should not interfere.
A few notes for the repeat job at LLO:
Tools required; 1/8, 9/64, 3/16 Allen keys
(It is helpful if the 1/8 key is cut down on the short end but not required)
-It is not necessary to completely disassemble the baffle assembly. Only the top side needs to be removed, however it is helpful to loosen all screws that don't need removal.
-After removing the old plate set it down on the HAM table in the correct orientation to remind yourself how the new one goes in.
-Leave all screws loose until the assembly is completed and then tighten.
