Auto to manual conversion

[MySons68C20]

I want to convert my C20 auto to a 4 speed manual....need the clutch pedal, cross shaft, rod etc.

[biketopia]

I have a whole peddle bracket assembly for a manual truck, I'm on the east coast so I'm not sure if it's worth it to ship. But let me know and I can get pics and prices.

[MySons68C20]

That would be great if you don't mind.
Thank you!

Are you interested in shipping the whole set up, or just pieces? Both pedals pivot correctly

[MySons68C20]

I can't tell if I can bolt the clutch pedal, spring mount etc to my current automatic bracket or not?

[biketopia]

I have my auto cab at work. I'll take this out to it tomorrow when I'm back at the shop and compare & contrast the two. Units someone else knows

[MySons68C20]

I'm trying to figure all this out before pulling the trigger.
Thank you!

Yup, looks like the upper mount spring hole is not there on the auto pedals.

So I contacted Modern Drivelines https://www.moderndriveline.com/gm/vehicle-specific/
and they can provide a one stop solution EXCEPT the pedal to the firewall.
It is a hydraulic solution eliminating most of the the mechanical linkage.
If someone has a work around without having to change out the bulkhead (don't know what it's called) that would be appreciated.
Thanks bike for helping me on this!

So referencing the link below it says I can just add on.....
I'm kind of lost right now on best way to proceed?

Silver Sport Transmissions has a clutch pedal they claim bolts up to the stock auto pedal box without having to remove. https://www.summitracing.com/parts/IST-PAG-01001A
I am going to the hydraulic master / slave deal since the all mechanical is so tough to find.
Thank you biketopia for putting up my pms and indecision!

No worries & glad you got something figured out. You'll be real happy with the hydraulic conversion

Pulled the trigger on the Tremec TKX 5 speed kit with all the goodies.
It's supposed to arrive here end of next week.
I'll start a new thread once I do the install.

I would definitely be interested in seeing how the install goes. I am currently swapping my truck from 3 on the tree to a 5 speed with a hydraulic clutch. I had to fab up a plate and pushrod to work with my stock clutch pedal. I had no reference measurements, so I based positioning on how much clutch pedal travel I wanted. I have no idea yet what the pedal will feel like.

Nice job on the plate! Your rod and master cylinder position is quite a bit higher than the SST stuff. There's more than one way to skin a cat!

That's one thing I am worried about with my setup. I really had no idea where I should put the master vertically. I just sat in the truck and pushed the pedal and figured out how much pedal travel I wanted, then put the rod where I would get the correct master cylinder travel for the given pedal travel I wanted. I hope it doesn't end up too stiff. We shall see!

I think you are going to be fine.
SST says their deal is 20% less effort than the stock mechanical linkage.
Even if it's the same as the stock setup that's a win!
Please update once you get there.
