Trying to get an understanding of what will work. The BV #2 kit has the most documentation but is also no longer available. Is the stopper that was included in it necessary for a de-powered zenki rack or was it meant for those wanting #2 kit but retaining PS? All of the similar rack spacers offered now don't have that stopper and say "manual rack only" and don't mention the zenki PS rack exception BV did.
Could I run any of these "manual only" spacers on a de-powered zenki PS rack or is the only option the knockoff BV #2 kits on eBay?
