New 633CSI in MA

New to this forum. Have a 1984 633CSI with 5 speed, sunroof, gray exterior and red leather and 120K miles...all original. Owners manual shows original owner as Nancy Talbot, founder of Talbot's Clothing stores...kinda cool...although she died a couple years ago. I think the red leather is a spinoff of the signature red door of Talbots stores.
In process of restoring. Previously restored a '72 2002...love old BMWs.
Couple initial items...looking for location of windshield washer relay and cruise control relay.
Would love a rear wing spoiler, but it has to look original.
Driver's seat base has a couple rips...is this red leather available? Maybe someone has one just laying around...
Has a little tick under the valve cover...is it common and/or worth correcting?
I will post a couple pics once I figure it out...guess I can't just attach here...
Thanks,
Nat

Sounds like a nice car to start with. The red interior is hard to find but a interior shop can match i had it done but will differ from rest of seats so if you think car is worth it do all the seats or you can go dying them to match also
