This is just an impression, but the boot and trim ring in Pete's truck looks an awful lot like a ZF-5 boot to me, and the hole at the top where the shifter cane comes out does not look like it hugs the cane the way it should. I could be completely wrong but that's just how it looks to me.
That said, I have looked at a lot of junkyard trucks and I don't ever recall seeing any round boots. Maybe I'm just not remembering right but I thought even the SROD/SMOD/TOD had square or rectangular ones... I will have to pay more attention. 🤔
