Just popping in for a quick update. Nothing much has changed on my truck since my last update.

I ran into a problem tonight. While driving around today I noticed that the clutch started to feel off. It almost felt spongey. I ignored it and figured it must've been my left leg acting up again. Later on the clutch stopped functioning altogether. I had to float the gears to get my truck home.

Upon visual inspection it looks like my bell crank bushings have disintegrated. I think I already found some replacements, but I'd really like to see if I can get some bronze or brass bushings instead of plastic.

Sorry, but in my old age I have forgotten or never knew what bell crank bushings are.
Edit: Ah, perhaps for the TO bearing shaft.

The bell crank is what connects your clutch pedal to the clutch fork via two rods. It rides on 2 ball studs; one mounted to the engine block and one on the frame. The bushings sandwich the ball studs to keep the crank sturdy and centered as it pivots. I've attached pictures that hopefully help show what I'm describing

A mechanical clutch, I guess.
When did 1500's change from hydraulic?
