69-70 dana question

[DoubleDlover]

on a 69 or 70 b body dana.  what size is the pinion yoke nut? 1 3/8?  1 5/16?   thanks ron

[John_Kunkel]

On a passenger car it should be 1 1/4"...only the trucks had the large hex.

My dana is a converted truck deal but I needed a thin wall 1 5/16.     I bought an expensive socket from sears that I had to grind down before I saw a 1 5/16 for about $8 hanging on the rack at autozone I wouldn't have cared if I ground up or not....
