80 GMC C25- Manual or Hydraulic Clutch?

Just wondering whether my 80 GMC C25 truck with a 4 speed standard transmission is a manual or hydraulic clutch. How would I go about telling which it is, or does someone on the board know?

Thanks!

I bet it is manual like mine. You would have to have a slave cylinder for the hydraulic fluid

Should have a manual clutch. My 83 has a manual, my 86 hydraulic. Somewhere in between they changed.

Re: 80 GMC C25- Manual or Hydraulic Clutch?

It will be manual (mechanical) clutch like my 83. You can check a catalog, like LMC online, and see the graphics of what parts are involved with the mechanical vs. hydraulic clutch, then compare your setup to the one in the catalogs.
