6j x 15 steel wheels. But, my 1995 model was able to have wires as an option, which I took.
The Williams car is a little different to mine......
Head rests....I have the boxy ones.
Piping....not on options list
Wings....mine are narrow body, the piccies seem to show wide(r).
I'll try to post a piccie of mine later
Geof, that's a new one to me I've never seen one and it wasn't until I read the full spec through just now that I realised they were available at the time. Looking forward to a picture of yours sometime.
