You know it occurred to me that you are doing a ton of shopping and research to get the parts and components you need to get your 38 up to where you want it to be. And that perhaps you hadn’t seen that SBO has its store site organized by boat model.
Here is the link to the 38 section
https://shop.hunterowners.com//hp/model.php?m=38
I’ve found it invaluable as I work to keep mine maintained and to do upgrades.
If you don’t find what you need don’t hesitate to send the folks there a note, they are very resourceful and have been so helpful, even going so far as to find a source for a part I needed, or finding an alternative.
They’ve even gone so far as to question when I ordered something and they knowing I had a 38 were sure I’d ordered the wrong thing. They were right and got me on track so that I didn’t get the wrong thing and have to hassle with returns and reorders.
Hope you find it as useful as I do.
