Throttle cable and carb gasket/spacer questions

Dad and I are continuing to put his car together, got a few more things hooked up. I have 2 more questions....for now...more to follow Im sure!

1. Throttle cable, see pics....You can see the hole in the firewall where the throttle cable feeds thru and then the ball end of the cable slides in the bracket, but does it feed thru from the engine bay side, or come in from the passenger compartment?? See the end in the 2nd pic, it looks like there should be a "C" clip, grommet or something to fix it to the hole in firewall.

2. With the new Eddy 1405, the butterflys hit a little and I have a very thin spacer that will work perfect. Should I gasket one sideof the spacer?? Both sides??

Again, thanks for all the input dad and I both appreciate it!

Thanks
