Both me, and graveltrap on here, race at coventry, and both of us have the Ghea parts off Wraggy.
He also uses 1deg hubs from STRC in conjunction with the block.
I was using Losi hubs, but you lose adjustable wheelbase with doing this, and last night changed out to B44 hubs.
You also need bearings and crush tubes in order to fit these - parts 7933, and 7935
The hubs are plastic at the moment, but aluminium hubs in various toe ins will be available from next month, and I have some 1deg on back order
I think these are the hubs I fitted last night ( sorry, binned header car so can't check )
