I am installing a Tremec 5 speed into my 67 nova.  I am using a hydraulic clutch setup.  I am in need of a little direction as to the proper installation location of the hydraulic master cylinder.  Any input would be greatly appreciated.  

As far as I know, on the firewall close to the clutch pedal is the best place.

Anyone else know more specifics?  

Thanks Phil,  Since I posted this I found a link on the Classic Chevy 5 Speed website.  They have a detailed installation spec sheet that states exactly what you have suggested.  It requires some fabrication and reinforcement of the firewall.  I think I have a good idea where I need to start.  Thanks again  

I'm also doing a 67 nova hydraulic clutch install and need help. I contacted Classic Chevy 5 speed and they don't have anything for the 66/67 nova. Were you talking about someone different? Any help would be appreciated Thks  

here is an image of the clutch pedal linkage...

mustang guys have a simular linkage...   they install the master where the pushrod goes through the firewall...      they sometimes use a clutch master like a 1990 jeep wrangler.

other times they use an aftermarket master that usually has a 2 bolt flange on it... with a vertical bolt pattern... one company sells custom welded units with the mounting flange on a diagonal pattern.

you can probably extend the pushrod with some new mini ball joints ...  this would give you ajustability...    you also might want to make a bracket that has mulltiple holes untill you get the ratio correct...

hope this helps...  

The 67 Nova is a real bugaboo for using hydraulics because, unlike other cars of its generation that has a small hole for the clutch rod to pass through, the early Novas has a big peanut shaped hole that accommodates both the clutch rod and the steering column.  I have been putting hydraulics in muscle cars for quite a while and on this car the easiest way to make it happen is to weld a plate over the lower section of the existing hole and create an area for the mounting of a master cylinder.  Several companies including The Driven Man and Classic Chevy 5-Speed offer kits to put the master at the right angle once you have that plate in place.  Hope I have offered some good insight.

Now for my related question.  Does anyone know where a fella can buy mechanical linkage for the early Nova.  So far I have not found anyone who re-pops this set-up.  Thanks for any help you might have.
