Okay, what pigeonhole is the right one?

I am looking for a Chrysler special tool. I look at the available forums. 'Cars and Mopar Parts Wanted'. Well it doesn't fit there. 'Other Stuff For Sale or Wanted'. No, not really there. So I posted it in the 'Shop Supplies, Tools, and Equipment for Sale'. This morning I get this:

Your thread Wanted: Miller C-3824 was deleted. Reason: Looking for parts or tools? Please start a parts wanted thread.

Start a parts wanted thread....where? And I would point out my post wasn't moved but deleted. So back to the question, start a parts wanted thread where? Thanks in advance.
