Ross' info from his FEBO thread... I first have to fix some transmissions issues created by the previous owner, I have a rebuilt 1971 833 transmission built by Passon performance to replace the 1968 transmission that’s in it now and a correct Hurst rebuilt shifter mechanism, I noticed the wrong length clutch pivot fork (too Long) was installed and as a result the driver’s side head pipe is half hammered shut to try to make it work correctly (which, it does not).
i hope you don't mind Ross
