Anyone already have one of the Miller Specialty Tools #8863A or B, or MB $140 15 21 AT fluid check tools?

If so, could you please measure the length for me? Thanks.

{Our ATs are MB's 722.6 's?}

P.S. I see a rebuilt AT on eBay for $100! Can't vouch for the seller in KY, but seems like a great deal if the correct trans. The auction number is 170361752551.
