Anyone have pictures of their clutch linkages and components? Pedals too? It would be great info for those who are doing manual trans conversions. :wave:

Cool, Thanks :waytogo:


Here are some stock photos of parts I 'm looking at on RockAuto.com
I'm using 85 K10 w/ 350 motor to get these part #'s since I know 85 used a Hydro Clutch. I'd still like to see pics of them installed so I get an idea of where they go on the firewall and what they look like in the bell housing. And obviously I'll need to acquire a fluid resevoir too.

Ahh OK. There is an assload of room with the Z bar that far back. I'm thinking of my 64 GMC. The Z bar pivot ball actually is threaded into the block. If you've ever wondered what those 2 holes are on the driver side of a Chevy block, it's 2 different holes for the Z bar pivot ball. In this case, the pivot ball is actually behind the block on the edge of the bell housing. I thought I seen that on a manual bell housing pic.

Anyone got a pic of a z-bar out of the truck, 81 short wide C10 in this case? I have something out of whack on mine. The short rod to the clutch arm runs off at a funny angle, inward and down, just doesn't look right. Clutch arm too short or arm on z-bar too far from bell housing. everything new except the z-bar itself. Wondering if the z-bar I have is from another Chevy altogather.
Thanks, Bob

I got a couple questions about this setup.
Is there a difference between the pedal assembly for a hydraulic and a z bar?
And is there any way of telling exactly where the clutch master cylinder is supposed to be located?

I converted my truck to a 4 spd with hydraulic clutch, and I've had no luck at all with it since I did the swap, I've gone through a couple clutch master cylinders because the rod from the clutch pedal to master keeps bending right in the middle. I'm not sure if there's supposed to be a certain angle it's supposed to be at, or there's something else completely out of whack. I NEED HELP!

I am almost certain the pedal assemblies are in fact different between z bar linkage and the hydro clutches.

It does sound as if you might have the hole for the clutch master misaligned. I was hoping someone could make us a template or give us measurements to make our own so we can drill the hole in the correct spot.
