I'm the welder in the video, we are planning to do some more filming on the truck in a week or two. we are starting our own YouTube channel doing projects like mine and doing some features on some local custom cars and trucks
Get yourself a plasma cutter man.
I hardly ever use my angle grinders to cut steel anymore. Only to round edges and refinish stuff. Ive got a Miller Plasma cutter and man that thing can blow straight through 1/2" steel. Those floor boards would have been cut out in about 25 seconds with a perfect line and the best part is you don't breathe in all that carbon crap from the cutting wheels.
Love the progress!!!!
Anxiously watching your progress. I picked up a 79 that I want to bag and transplant a Viper Gen III into.
