I picked up a new 3.45 crown wheel and pinion off eBay about a year ago.
There is a guy in Cheshire, UK, who sells them occasionally. I put a search
marker in eBay and it flagged me when it was up for sale. I think I paid
GBP105. It was a second chance offer so they guy must have a stash of
these.
I had tried to get a used diff from UK scrap yards when I was over there,
but it is increasingly difficult to find old Triumphs in the general (aka
cheap) yards, unless you have some pretty good local knowledge. You can go
to one of the specialist Triumph breakers, but they want more money than I
was willing to pay for a whole diff, and they wouldn't sell the CWP alone.
I do have an A type overdrive so I'm not sure I will ever install the lower
ratio ... but after the engine rebuild, maybe I'll have so much power that I
could use it!
