What size is the kingpin cap bolts? I measured and gave it a glance and it looks like a 1/2 fine thread. I would need a
1/2UNFx2.5" bolt. Can anyone provide a little more info?

Also, can a regular grade 8 bolt be used to bolt the lower kingpin bearing and upper caps on? Ive searched to find a whole contraversey over this. Some are doing it fine, and some say its unsafe. Any final words?

Im using the avalanche hysteer arms and need a longer bolts so the stock size wont work with my application.

BTW, its a 79 ford d60r drw

thnx.

Yes thier 1/2" NF. I used grade 8 all thread and a self locking nut to do mine. Grade 8 hardware top and bottom holds up fine for me. Even broke a knuckle and the hardware survived.:)
