Vacuflush model 858 bowl leak

I have 2 Vacuflush toilets in m 1998 Carver 355. I rebuilt the aft head latest year. New ball valve, bowl seals were done then. Bowl has leaked since.. Eeewww! So, today I replaced the water valve which has been dripping. I moved the bowl, so I think the clamp was loose. I pulled the bowl and found white crusty stuff n both rubber and Teflon gasket. Took them outside and scrubbed them clean. I lined up the notch and installed the thin one with smaller circle in the middle first with this side up, then the thick rubber seal with smaller hole on top, lining the notch. I put the plastic collar back on, centered the bowl, then cinched down the clamp. The bowl doesn’t move. The water is holding vacuum and pump shuts off. When I push the pedal down, some water seeps out at the bottom of the pedestal.

The model toilet I have is an 858. It’s 1998 vintage. I purchased the set without drain holes. I noticed the after year 2000 uses no drain holes. Is this my issue? Do I need drain holes?

Use bowl seal kit #385316140 with over flow holes for model years 2000 or older.
Are you sure that your model # is 858 instead of 848?
