Lincoln pinion backlash

I'm in the process of setting up a Lincoln [hypoid] rear end. I'm quite familiar with how to set up a banjo rear, having done numerous Fords over the years, but I don't know the specs for backlash between ring and pinion for a Lincoln. Does anyone have the specs? [measured at the spline]. Thank you!
 
I have it written down with other notes and bearing and pinion seal number from when I rebuilt my 39 Zephyr rear axle. . I’m away from the shop now but maybe later this afternoon.
 
Think those parts came as an assembled pinion/ housing and ring gear so no specs were published. At least none ive been able to find. I would say tooth contact pattern is more important than lash with those
 
I finally found the information I was looking for.

thank you Ken and Pete, I actually set it all up and fitted it a week ago by reading the gear mesh pattern. A bit of work with the Columbia, I had to fit a .005" shim behind the Columbia side bearing cup to move the entire assembly over an additional .005". Originally, I set the side bearing preload, that only required .006" gasket thickness in total. But ring and pinion mesh was too tight, even with no gasket on Columbia side. Hence the fitting of the 5 thou shim and additional .005 gasket to maintain preload. I'm still awaiting delivery of the GL4 gearoil before I run this thing, I'm hoping it's good!
