I did do a quick search and a 65 Dodge truck does call for a slave cylinder, so that setup looks correct, what is interesting is that there is a threaded ajustment on the linkage, you could try to adjust that rod, this adjustment would compensate for the clutch disc wear that I mentioned earlier. I would look for a shop manual with the procedure, but looking at your clutch slave cylinder movement Id say it needs to be longer. You could try that before installing a clutch. It is called 'clutch free play ajustment" in most shop manuals. Check this link out, it is about Clutch free play ajustment : Sweptline.ORG • View topic - Clutch adjustment on a 67 d-100 4 speed w/ granny gear?
I was thinking it needed to be longer as well. I just call hr clutch and they were able to find a clutch for me and I think I can order a whole new system through them including the fork and rod set up they do want me to get the clutch off and send pictures with measurements to be sure but they looked it up in a catalog for me it's a 12 in plate is what they have so I'll probably take it all apart I'm sure if the slave cylinder isn't correct I could get that through them as well. Thank you everyone I belive I have been connected to the proper people to get what I need and have a bit better understanding of what's going on I have a mechanic coming over tomorrow and I'll be able to tell him what I think is going on he can look at it and hopefully we can move it to where we can get the work done in the next couple of days. I really appreciate you all taking the time in talking to me!
