I need some ATI parts right away and ATI told me they are on back order, Summit is out as well.
I need - 1 x #406000, 1x 405721, 1 x 405371B (or Sonnax 34322-02K), and 3 x alloy bolt in intermediate snap ring supports, all for TH400. Would need them shipped to the UK. Thanks.

I see you are in the UK. Might give BTE a call and see what they can do for you. They have a dealer in Sweden, Stig Olsson Stigo Motorsports. I know he stocks a lot of transmission parts he may be able to help.

 

Sorry but only stock PG parts but pretty sure that BTE have the parts you need.
