Restoration for 4907 European GTS from 1972/3 is on going ..here my question on internal material for the sealing and adjacent parts.
Currently material is perforated and has an off white color/elephant teeth color and has a sponge rubber layer.
I want to replace it..
1) is this the correct color - off white?
2) is original perforated?
3) is surface smooth or does it have a pattern(see belwo samples)?
3) does original have the sponge layer?
I am looking for something like this..(picture)
Tx for help!
