Interesting Junkyard finds
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? |

American,
The dual master cylinder setup with the passenger side clutch is normal for the '60 pickup with an SM420. I've got one just like it Brian |

Re: Interesting Junkyard finds
Like Brian said, the dual master cylinder setup was very common. It was used on all 60-62 trucks with manual transmissions, even the 3 spds. The pickups went to mechanical linkage in 63, but many of the big trucks still used the hydraulic setup. My 65 C80 still has the hydraulic clutch with the dual master cylinder. There were a lot of the 3/4 ton and I think even a few of the 1 ton Chevys with rear coil springs. All of the GMCs had leaf springs in the rear.

Re: Interesting Junkyard finds
Has anyone ever tried to flip the slave cylinder upside down and use it on the drivers side?
I know coil rears are common in 67-72's of the 10 & 20 series, it's just the track bar that looked out of place on that truck for some reason. |
