i am converting my hydraulic clutch to a manual clutch, for my recent auto to manual tranny conversion. Where do I drill the hole in the firewall for the clutch rod to pass through and how big should the hole be?
This is in a 1973 hornet. Thanks for any help in advance Dudley

Isn't there a "punch out" pressed into the sheet metal for it?

I did not see one, but it was getting dark. I will check
just from eyeballing it, it looks like it should be about 1 1/2 to the left and about 4-5" down from bottom of steering wheel shaft |

There should most definitely be a punch out for the pedal rod to go through the firewall. I just did my punch out this past weekend on my 73 Javelin. Look on the firewall for a 1-1/4" knock out with screw holes above and below it, maybe on a slight angle. That's where the pedal boot screws to the firewall. Much easier to do from the engine side if there is no brake master cylinder or booster in the way. It punches from the inside out though. I have my whole dash out because I was adding the pedals at the same time.

Finally had a chance to check. It's there exactly where you said. I didn't see it but my son did.
Hopefully get a chance to work on it this weekend Dudley

I've owned a few '60s International pickups with the "juice" clutch. My advice on a hydraulic clutch starts with a question: Do you drive the vehicle more, or does it sit more?
Because if it sits a lot, the "sealed" hydraulic system will somehow manage to lose fluid. If you drive it a lot, and do regular maintenance, the fluid disappearance just doesn't seem to happen. If your car sits more than it's driven, the mechanical linkage is the way to go. Your experience may be different than mine.

Buzzman72...void where prohibited, your mileage may vary, objects in mirror may be closer than they appear, and alcohol may intensify any side effects.
