I received Mike's mechanical throttle linkage in the mail a couple of weeks ago. Very nice piece. Also spoke to Mike on the phone and really nice, helpful guy!

I'm getting ready to install my firewall, but wanted to check to see if I needed to do any drilling for the linkage prior to installing the firewall, or does it all need to be done on the car after everything is hooked up? I looked around and didn't see a 'How To' anywhere, so if anyone has one, please point me in the right direction. Thanks!
