98 Z-28 automatic to M6 conversion

How hard is it? Don't these cars have the removeable transmission tunnel holes for the shifter and hole in the firewall for the clutch slave cylinder allready? I'm intersted in doing this to my 98 but didn't know how I'd get the computer cleared from the auto to T-56. I've done a auto to M6 swap in my third gen but it was easy since there wasn't any computer to mess with and I had lots of time to piddle with it. My 98 is my daily driver though so I'd like to complete the swap in one weekend if possible. Thanks

you will need a tuning suite and reflash with an m6 tune or adjust all the tranny settings manually.
