Measurement Help!!!

Hopefully somebody can make this easy for me. Gonna have the rear end narrowed on my 77 1 ton camper special. Whats everybody's measurements for the rear end. Keep in mind I am planning on running 22's on all six wheels. The truck is bagged and 4 link'd and drop spindles. Let me know. Sending out the rear end tomorrow
THANKS

I can't help with the measurement you need but was wondering what this is going to cost you ?

Also is yours a dana 70 ?
