leaf spring hanger question

Cosgig,,,

the 8.75 going in is the one I bought from you a couple of years ago,,has the 742 large yoke center section,, cone sure grip..
I am rebuilding the center section,, all new bearings,, the the cones had not bottomed out, they were within .012 or so,, so I had them cut .030,,

for the hanger bolts,,I looked again,, for the rear hangers there is a access opening on the bottom side of the frame box,, I can use an inspection mirror to get a look at the threads,,

I am changing out the fuel tank,, so will remove that first,,

thanks all for the ideas.
