First, I forgot to mention that 8 and 16 ohm diaphragms were once available from EV`for the T35 but as far as I can tell they discontinued the 16 ohm more than 20 years ago.
EV was bought out and so went the 8 ohm diaphragms too. But if Great Plains Audio did get the jig to make them, they are the best bet but they would be 8 ohm as far as I know. You could call to see if they do offer the 16 ohm and when they might have some. Forget e-mail. They aren't good at answering them.
Any new T35 diaphragms you see on line are cheap generics unless they say NOS or new old stock.

The 16 ohm T35 and T35B are a fairly common item on E-bay but unless your lucky I wouldn't expect to see a pair for under $100 and then it's risky unless the seller gives a DCR reading for each or you may end up with another headache.
The T35B is just a less efficient version of the T35 with a smaller magnet and it was used with other drivers that were less efficient than some of their other drivers.
No sense in cutting back a T35 like crazy with a pot when the T35B was already less efficient.
The T350 used the same diaphragm but it was more efficient than the T35 with a bigger yet magnet and it has a larger horn. Some consider it to be one of the best vintage tweeters even if it doesn't go much beyond 15KHZ like modern tweeters. What it does do it does well.
The caps aren't really in series. Yes, one end of each is tied together but that's the plus input to each and not a series connection. A real series connection would the two caps wired like they are BUT without the third connection that feeds both caps.If they were in series the resulting value would be about 1.90uf. And since you need a cap for the mid and a cap for the tweeter that would leave you with only one cap.
I do see that the 2.84 has one wire on one end and two wires on the other end. The two wires are tied together and because the cap is marked 2.84 that can only mean that there are two 1.42 caps in that bundle in parallel that adds the two values. The other end would be a common connection for the two caps.
