1st Gen Clutch Z-Bar

I'm trying to make sure what parts I need to set up a clutch linkage in my '64 small-block car. Looking at Year One's site, they list one part # for the Z-bar, and they say it fits 6-Cyl. and V8 applications. So is this correct? Is the Z-bar the same part for both Straight 6 and V-8 engines?

Also, Since all I have is a non-Nova engine block, do I need any adapter parts to adapt the factory-style clutch linkage on the engine side?

I could, of course, answer all these questions for myself if I was to mock it all up and just see how stuff fits, but my shop is uh... a bit busy right now with other projects that I'm trying to get out of the way so I can start on the Nova, so maybe you guys can help with a bit of info Thx!
