K04 to K03 Adapter

Doug @frankenturbo makes something very similar.

By all accounts it works well and allows you to retain an existing 3'' DP if you have one.
 
Cheers Prawn, yeah I have the correct DP etc. Presumably oil lines will be different than the K03 but seems a simpler (cheaper!) way of fitting a K04.

What would I do with regards to a TIP?
