Yuppers, that's how they do it. I need ~38mm under the lock washer.
Also just realized I can't add the length to the flange, it's the A750 bellhousing. I might need to revise the next version of the adapter to be 5mm thicker...
You could try ordering one of these as a test
91619 61240
It shows up as a valid part number.Toyota fasteners part numbers, the last 4 digits represent thread diameter, and length
So, that part should be 40mm.
Or 91619 61235 should be 35mm
