Sir,
Welcome to the club.
I have some U'Carrier bits - few for T-16.
The olde forum used to reference a guy in North Carolina, USofA who had some spares - mostly bearings and minor whatnots.
Sadly, I only have a box of NOS carb float bowls for your restoration. I will be happy

to give you 1 ( or all) should the time arrive when you need them. If, heaven forbid, there is a run on these, and they increase in value 1 million times - I will still give you all you want.
