Thanks for the nice comments. I will answer the questions that I can, but because the PO restored the car, I don't have all info or may get some wrong.
1. The springs are from Carl Nelson
2. The steering wheel is a Nardi
3. The wheels are from Peter at Coupe King
4. I don't know what the brake components are or where they were sourced.
In terms of next steps for me, the car is still carbed and I'm thinking about upgrading to 1.3 motronic FI. There are a number of nitpicky items that could be improved but aren't urgent. They include door alignment, several interior trim bits, non-working radio and a squealing ventilation fan.
I will post additional interior pictures shortly.
