found the part! now my only question is are the floats the same on the middle and bottom carb? may be a dumb question but first time doing this
Yes, they are; the floats in all 3 carbs are the same. Haven't personally seen a lot of failures in the newer-style plastic float, but things do happen! The hollow-chamber style of that float would make it more prone to getting a leak and filling with fuel, whereas the older foam-style-plastic floats just tended to soak up the fuel and get "waterlogged".
If you're going thru the carbs, it's always a good idea to check the floats, set the float level and make sure the needles and seats seal like they're supposed to, and flow as they should. New needles & seats are still available, BTW, if needed.
FYI that same float style has been used since the 50's, ain't that a kick!
Something that I didn't know, I checked and the hollow-style float has been superceded by an even newer-style float, that looks like foam again. Maybe the hollow floats were springing more leaks than we knew.
That being the case, it might not be a bad idea to order (3) new floats, to avoid problems in the future.

p.s. the Sierra Marine aftermarket floats (P/N 18-7208 are a lot cheaper!!) And lots of times you can order them thru NAPA.
