LeTourneau PCU for RD4

Hello, 
I am looking for the shive tower for the PCU on my RD4, as you can see its missing from mine, and it will be awfully hard to tow and operate a scraper behind it without the shives. I would consider an entire PCU that would fit an RD4 or just the shive tower, which is common to almost all LeTourneau double drum PCU's.
Let me know what you might have available.
Thanks 
Nathan

Hi Jeff, 

Thanks so much for the reply, I have found one since posting this.  However the earthmoving legacy center is looking for one, so I passed along your contact information to one of the folks there.  If you have someone reach out from there, that is why. 
Thanks again
Nathan
