You should be able to find a used divider plate somewhere. Looks like a new one is going to be a challenge though. If Sea-Way marine and ebay don't have it you know its going to be hard to find. Its probably harder to find on ebay under that part number. Best bet is to just bring up every V6 exhaust divider plate you can find and spec it out for year. Not something that is generally going to be listed by part number when its used.
Yeah I called seaway a couple days ago and they didn't have it and no luck on eBay either doing it the same way that you say. Might be better off finding another boat
