Actually took the time to read through this instead of keeping up with you on messenger. Just a few words about it honestly, so here it goes...
GOOD. FUCKING. JOB. MATE.
Seeing this keeps me inspired to do stuff like this the correct way and spend the needed money on quality parts and not skip corners.
Maybe once I get my sr20vet in mid 2020 that ARC plug cover will be up for you if you haven't found one yet.
Keep up the good work mate. Been a pleasure to know you for these short years that I have.
