Looking at the picture the hardware looks fairly common and you should be able to match it up with new or just be on the look out for used hardware, make sure you know the measurements of your turnbuckles etc. You may see the hardware identified more by manufacturer than by builder. Glenwood made a ton of this stuff back in the day as far as turn buckles, NICSON also made them, the NICSON Turnbuckles are a little different, ill post a picture of my Spectra which has NICSON Turn Buckles (I bought them used from shop in Phoenix, I found them on ebay)

The plates look to be aluminum and you can sources these pretty easy at most any steel business. Aluminum is easy to work with to cut and polish or if you want to step up to stainless plates a bit harder to work but you can still do it or enlist a shop to assist. The best thing about stainless is if you want a polished look, you do it once and they are done with some occasional light polish. For me the cav plates on a v drive are a beautiful thing and you can go crazy or simple, I like simple and clean probably because I cant afford Crazy :)

Here are two examples, my Sanger has aluminum plates, raw, no sealer at all just polish and they need some attention. My Spectra has Stainless, they were polished in 2014 or 15 and I don't touch them with anything heavy or labor intense, some good metal polish wipe on wipe off. The Sanger was put together in 96' so when I play with it in a few years the plates will go stainless.

I agree, you will be hard pressed to find one off of a matching boat. They didn’t make these boats like cars rolled off the assembly line. Also, many were finished by the owners and each was just a little bit different. If yours does not have a recess under the back of the boat then it looks like you will have to use the angle to mount it. As said, use aluminum or stainless for the plate. As a rough guess, I would probably extend the plate 7 or 8 inches off the back of the boat. As far as the rest of he parts, if you can find parts stripped off a boat with similar dimensions that might be the easiest for you. Buying the parts individually can get pricey. For a budget build that is what I would do. Watch eBay and look through the for sale ads here and on Facebook. Take good measurements of your transom so you can make an educated purchase.
