I have a 65 and in a fit of youth I put a chevy in it now I'm replacing all the stuff I took off of it all those years ago. Well I had most every thing I needed however I cut the linkage peice off the frame that is welded (OR WAS IN MY CASE) on the frame bellow the base of the steering colum that converts a forward motion from the clutch pedal rod to a rearward motion that attatches to the clutch fork linkage under the car . So my question is how long is each arm of that aperatus?I'm a professional fabricator ,so I can build it but I need to know what pivit ratio it needs in order to actuate the pressure plate and still have free travel at the top of the pedal motion.
ummm, the bracket is basically flat stock, the actual "conversion apporattus is the "Z-bar" and is avalable, do a quick search here and you'll find what your looking for. Jon
Well, its not going to be easy. I converted my 66 to 4-spd (same as 65), and the clutch linkage parts are not available anywhere. Everything must be fabbed or procured from a donor vehicle. the chassis manual, shows all the parts. The frame bracket wont be too bad to fab, but you really need one to compare. Placement on the frame can be done if you get pics and measurement from someone doing a resto. You will need to remove the inner and outer fender, or your master cylinder/brake booster. I had good pics and measurements from Eric Hubbard, when I purchased his parts. If you need them, I'll try and see if I still have them. Good luck.
4 speed Well I did get one made over the week end,The arm comeing up was easy as it had to be long enough to attatch to my factory clutch linkage rod comming through the firewall.The lower however was not as easy because it needs to be the right lenth to stroke the pressure plate enough to release the clutch and also have enough motion to pull the throwout bearing away from the pressure plate when not in use. I think I'm close enough to work with at this point .
If you can fab up a kit with clutch linkage parts for 65-66 GS's, I would think you could do a good bit of sales through here, and ebay.
65 gs linkage Good evening, this is the first time I've used v8.com. I stumbled on your linkage question and had a few of my own. I also have an original 66 gs 4 speed that some short sighted person converted to a chevy. I have collected most of the parts but need the lower frame bracket{the bolted one} and the lower linkage rod. Any measurements thoughts tips or suggestions would be greatly appreciated. And if you are an experienced fabricator I would gladly buy said pieces from you. Thanks a million jbh :3gears:
Brian, great pictures! sure is a lot easier to see, and get at, with all that sheet metal out of way! :beer
Brian , Great pic's These are original correct? I really appreciate this, I should be able to get a good measure of length on the lower push rod. The lower bracket however, I need to find someone who can fabricate that. Then I am in business! It's very frustrating becuase one of my parts cars had the complete set up in it and I let it slip through my fingers. The guy asked if he could keep it for a street rod if he knocked $400 off the price, at the time I was planning on putting my 69 400 in it so I let it go. I had no idea at the time how unique the parts were or how rare a nailhead 4 speed is, damn that hindsight! Any pic's, measurements, parts, or lines on a fabricater would be greatly appreciated. THanks again Brian! jeff
