1972 C20 Clutch Linkage Assembly (Parts)

[corp-mule]

I need to replace the upper clutch push rod on my '72 C20. Does anyone know where I can get my hands on a good diagram or parts list for this?

I've found several web sites (LMC, Brothers, American Classic, H & H Classic) that have the upper push rod and other clutch linkage parts but, I can't find the nylon (plastic) bushing(s) anywhere. Any suggestions for where to find this will be appreciated.

I must admit, I don't have my truck in front of me. I took it to a shop and I was told these parts were needed. I don't know much about it. So, maybe I'm asking a really stoopid question but, it's part of learning.

Thanks in advance for any help.
