It's worth mentioning here that between the throttle control panel location and the bracket on the engine, the cable itself will assume a very specific angle, especially with the firewall sleeve permanently swaged at that precise location. Here it simply made sense to purchase a DoubleTee Products firewall ball-pass thru grommet (brass-colored fitting top right) which can accommodate any angle the cable assumes as it passes through the firewall. Very easy to install and really well constructed. In retrospect I would have used this for all the pass-throughs.
