Need some help. My 770 was in the shop with the rear wheels off for a few years. Went to put them back on today and discovered I bought the wrong lug bolts some time ago. I need 5/8" X 1-1/2" ,11-coarse, but have 9/16" fine. Unfortunately I threw the old bolts cause its a restore. Now Im without bolts and cannot find 5/8" lug bolts online or anywhere. Are these bolts now obsolete??? I would not know why considering all the other applications for 5/8 lug bolts and the number of 770-880 tractors built.

Thanks
 
I sent you an e-mail. Did you receive it? Those 5/8 bolts are just plain grade 5 or grade 8 plain bolts. You have a late set of hubs & wheels.
 
My rims are tapered at the Lug holes. You might be thinking of 1550 hubs. The bolt I need is part number 103 959A. regular hardware bolts wont work. My 770 is a 1962 model.
