Hey Ryan - I post my stuff on zclub.net (I'm in the UK) and lurk around on here. Just wanted to say how much I'm enjoying the videos and work you're doing. I'm renovating a '73 HLS30 and, like yourself, it's my first time doing any of this stuff and totally agree with you: how on earth did people manage before forums?! As a nod to my US cousins, this site is extremely good with so much great information and advice.
I just bought some panels from KFvintageJDM and I'm super impressed but I'll guess we'll see how things go as I'm just.starting on replacing the floor. I also just built @ConVerTT's fantastic jig design and I'm so pleased with it. My welds are nowhere near as good as yours though as I fell into the traps that you enumerate above and blew holes in numerous places! Still, it seems very solid though.
Keep up the great work and looking forward to following along!
Jon.
