Alright, not that there has been tons of success to report. But still, what ive done meanwhile is, glued on some soundproofing. Cleaned the wiring loom, and am now in the process of putting the wiring back into the car.
Today i found out that my parts car has speakers under the dash aswell. Removed those, but as you might guess they are quite old and generally in bad shape. Mine had none, so I definetly want some now.
What i dont have though, is the thick floor mats that are under the carpet, covering the footwells in front. Probably impossible to find aswell.
This is it for now, I will try and make some photos tomorrow.
