Hi Mike,

Both of your attached photos were of a straight SS chainplate.  It looks like it will work fine.  If it’s too long; then, cut to length.  I just removed the SS cover on the opening where the chainplate exits the cabin roof.  I was able to use an abrasive cut off wheel on a Dremel moto tool to cut off the old chainplate enough to slide the new chainplate past it thru the same slot.  If you don’t think that’s going to work on your boat; then, please send some pictures.  I also don’t understand why the new deck inspection plate doesn’t give you access to the backside of the chainplate?  Please send a picture.

Unfortunately, this does hole not give me any access to remove the old chainplate. Was your configuration different than mine, or am I missing something?

Cosmetically, I’d rather have the new chainplate inserted through the slot where the old chainplate is, but that requires removing that part of the old chainplate first.

I found a Ronstan chainplate that is virtually identical to the Rhodes OEM part except for being 2” longer (https://atlanticriggingsupply.com/products/roch16ga208l?variant=17547140333614 <https://atlanticriggingsupply.com/products/roch16ga208l?variant=17547140333614&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gclid=CjwKCAjw3624BhBAEiwAkxgTOokHnONhod708mwSxS7JQDkABFLyrLt1Lg5eVFrqJT8XMNpL9oNZGBoCeBAQAvD_BwE> &currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gclid=CjwKCAjw3624BhBAEiwAkxgTOokHnONhod708mwSxS7JQDkABFLyrLt1Lg5eVFrqJT8XMNpL9oNZGBoCeBAQAvD_BwE)

From the hole in the cabin wall, you will be able to remove the old chain plate.  The new chain plate will just be a straight piece of SS bar stock and will use the same hole thru the cabin roof as the OEM chainplate.  The new chainplate will be thru bolted thru the outer cabin side wall.
