Here is a picture for comparison.
Not sure that I can confirm nor deny being able to use the OEM AT pedal with the clutch pedal or not.
Honestly I would NOT do that. There needs to be the appropriate spacing between the brake and clutch pedal for safety. If that combination could be used I'm sure they would have done that from the factory....but they didn't.
I'm a firm believer in one thing on swaps...... do it right or not at all :shrug:
*** for the Clutch Master hole in the firewall ***
1) I used a right angle drill to drill a series of holes around the perimeter of the pre-cut/punched Clutch master hole.
2) I used a Dremel to cut out where I could
3) for the remiaining material I used a die grinding bit and sanding drums to clean up the hole
