The Stovebolt Site Forums The Parking Lot Big Bolts 1966 GMC L4000 Tilt-cab brake parts

3B, Thank you so much. I think that's my issue - maybe its not a 1966! I just assumed it was based on the title. The WC19746 definitely looks like the correct wheel cylinder. These are also cheaper which is nice. For what its worth, the SPID shows that this rear axle is a rockwell g361. I'll try to find a axle ID plate to confirm.

I'll update again once parts come in.

Again, thank you!
