CLUTCH HELP UPDATE
is there a way to tell which one it is ?
yes;
but I only know about the 67 and up, A-body cars so if you have something older, or NOT stock, Brewers is the place to go.
The ratio thing has been discussed here on FABO several times, and pictures were included; so try a search.
The difference is at the very top of the pedal, and IDK if you can see it, once it is installed. But in your case it sorta seems obvious, that you have a ratio problem.
The slanty cars came with a smaller clutch, and a less stiff assembly, and so did not required a lot of leverage; but the bigger/stiffer V8 clutches did.
The slanty pedal can be modified by cutting and welding
