Neck Queries

Hi guys,
I am a proud owner of a Matsumoku Westone Thunder IA. Possibly my favourite thing about the guitar is the neck; I am planning to build a guitar and would be looking to either buy another westone model and use that neck, or use a neck with similar dimensions. Therefore I was wondering; are the necks on all models of thunder (the IA, IIA and also the non-Matsumoku models) the same dimensions? If not, I'm wondering if you guys know or would be able to point me in the directions of the information regarding the dimensions of the particular neck so that I can try to find one that is as similar as possible. Also, I really like your site, the guitar is my dad's so I didn't know much about it and he got it when he was younger so finding this site has been helping both of us learn about these magnificent guitars! I look forward to hearing from you.
Thanks,
Ross MacLeod

Hi Ross, and welcome aboard! 
If I recall correctly the thunder ii models are set neck guitar, tthough I could be wrong there. 
I think all the thunder 1 versions are the same however. 

Adey that "left hooker"  is pricey, I just bought a complete T1 for just a couple £ more.

I thought it was a little pricey too. Only one photo. Difficult to see frets, but they looked a bit tired...
