Dan,
Those pics are great.
I am looking for the measurement from the back of the bellhousing xmember to the center of the front hole of that lever bracket. It looks like it is right behind the cab mount hole from your picture. I could also use the measurement from the back of that same bellhousing crossmember to the center of the Master cylinder filling cap. By back of the crossmember I am taliking about the vertical edge.
As an alternate measurement... the center of the top rear rivot of that bellhousing crossmember to the center of the front rivot or bolt of that reversing lever will also work. Where ever you can get a measurement along the frame would be good, just let me know where you are going from. The bellhousing crossmember is a good reference point.
Thanks again
John
