| I don't know where to find one, if you have a local tractor graveyard you could try there. Otherwise maybe the more experienced members would know? |

| Keep us posted on this. If ARP has a replacement, would you let us know? Or post the p/n of the original bolts/nuts, if still available? I’m strongly considering replacing mine before final assembly. Don’t want to take chances after all the headaches it has been getting this far. |

| arp is sending me one bolt to see it it will work , it sounds like the nut will end up exactly flush with the end of the bolt. think we will machine the rods and cap just enought to get a full thread past the nut also the grip lenght is about 1/8 longer that shouldent hurt. because thier is only an 1/8 grip in the cap . if it will be ok they have plenty and they cost exactly 10 times less than the oem , dont know who makes the oem but the arps should be the best we are going to get |

Oem p/n’s are 74515070 -bolt 74516821 - nut. They appear to be pretty pricey. At one time I had an NOS connecting rod, and it did not have the castle nut with cotter key on the rod bolts, like the originals. It had a crown lock style locking nut, and there was maybe one thread protruding, if that. I’d assume that if the bolts/nuts were ordered from AGCO, they’d be the newer design. Hopefully the ARP’s will work. Post part numbers if you would, once you get them verified. Thanks |

| Hudco, any chance you’ve received your new ARP rod bolts and could share the part number? |
