I recently got a Zone Six tripod without a head.

This tripod is made of Ash and can take much abuse, just perfect for planned world travel with my 4x10 outfit.

I have several cameras and heads that fit in the Linhof bowl of 90mm diameter like in the big Linhof tripod from the 1960's.

I am trying to find a bowl of 90mm diameter that will be the head for the Zone VI tripod.

Should I just remove the bowl from the big tripod's column? Is that practical?
Can you point me in the right direction?
