How to plasma cut a C notch using the CNK6372 kit 1963 to 1972 Chevy GMC trucks. POL inc

I did my first job on a vehicle which was a C notch install on a 1970s chassis. The C Notch kit is from performanceonline and is model cnk6372. I used my Miller plasma cutter top get the C notch made in about 2 hours. This is the first time I see one and took a bit of tinkering before I actually started cutting. I hope you enjoy the video and hope it helps out people.

Thanks for watching and cya in the next video.
