I have a few sets if you can wait for me to hunt them out.
Those stainless steel capped nuts in the picture are used on mid 80's 240 cars.
The ones that you want for 140 are domed and chrome plated. I will be able to take a picture. It's a little difficult to put together a good set these days, but there might be something similar aftermarket? I take it you are doing a faithful restoration?
