Interesting Junkyard finds

[Americanrider]

On my latest trip to the local pick & pull I noticed a few odd things.

1st was a mid 60-something C-20. Can't tell the year but looks like a 65-66. Very hard to tell since it had a cab fire and no grill/hood. It has a Eaton Full foat rear on coils and a track bar. I have only seen Tack bars on half tons never on the big eatons before. Was that common?

2nd was a 60 or 61 (big eyebrows w/lights in center cross) and it had a dual chamber Master Cly, one side was for the clutch the other side for the brakes. The line for the hyro clutch went over to the pass side slave cylinder of the bellhousing.

I have seen this type of hydro clutch setup before, I had one my (early) 47 Chevy PU back in high school, but it went to the drivers side of the bell like regular GM stuff. My 47 truck had a 283 & T-10, 56 Chevy Car rear, 53 car front hubs.

Just trying to improve my knowledge of all the the year groups. Any comments?
