One is marked truck the other isn't;
Ruckstell shifter bracket reinforcement.
OH crap... I attached my Murphy rod to that bracket to help hold up my muffler bearing! I guess I'll have to take it all apart again.
I don't know when they started using those, but I think it was after Eaton took over Ruckstell. Check with Glen Chaffin, he would know for sure.
Thank you everyone. I said they weren't Ruckstell but with reservations that they might be to the guy that has them and was asking. I will let him know.
Here's a photo of the "TRUCK" reinforcing bracket attached to the Ruckstell shift lever.
Thank you Rich. The 3rd hole had me wondering what it was for after I was told what it was. Thanks for showing how it fits together.
