Take a nice clear shot of the RF section when you get the set. These appear to be trimmers, but are not mentioned in the alignment instructions on the ARF scan of the Riders on this set. Agree, probably OK. I'd leave them be until after the restoration is done and see if alignment goes well.

You can get a much better schematic and notes set from Chuck's site
