Dave from SWISCO responded:
I suppose it could be done, but I've never tried it so I'm not sure what it would take. Personally, I would stick with the 84-001. If the original builders used this, then there is probably a reason for it.

They might get better results with a new set of roller adjuster parts. 84-512
