Axle bolts ordered

Just ordered the socket cap bolts I needed to complete the axle shafts.  Their not a very common sized but I found what I needed from a place in Massachusetts.

The new addition.
2001 FORD F-250 SUPER DUTY LARIAT. 
It was a 1 owner (85yr old)with only 71,000 miles.
This will be our new tow vehicle that will replace our old van.
Been working on it for the past couple of weeks , brakes, ball joints shocks. etc. It has the tow package rated at 9000 lbs.
