I would replace the points if you haven't done so already, they have a habit of going on strike even though they look OK.

Hi Jamie,
Welcome to the forum.
That's a nice project you've got.
These guys should be able to help with parts/info :
https://johnshirtmotorcycles.com/
If you would like to PM me your direct e mail address I can send you an owners manual and parts list which should help with the rebuild.
If you can't source replacement stanchions, these guys seem to do a good job :

Thanks
Genuine Seeley, it even came with a nice authorisation letter from Colin Seeley.
I painted the tank cover and fitted genuine Seeley stickers and made a neat sidestand from a pair of Renthals, and generally tarted it up.
Made a neater silencer
It rode very well.
Hi,
Sorry I can't help but perhaps a quick whats ap message to these chaps might provide the answer.
They seem to stock quite a lot of parts for all models
