Check with K9COP. Not sure if he is on this forum but he frequents madmechanics.com. He has a really nice centre console plate and some switches. Not all of them nut a lot of them.
Lambostuff.com, I think that is the right URL, has OEM switches. Be prepared for the price though. Not for the light of heart....
. There are a few of is working out OEM sized curved door glass as well so the flat door glass will be history. More coming on that hopefully soon.
76mx has a couple OEM size Countach screens left from his last purchase and they are very nice. He really packs them well for shopping too. Pm me and I can direct you to other Countach builders that might be able to help as well.
Start a thread in Countach and keep us updated here or on madmechanics.
Cheers
