72 K5 wing windows and bright parts. Buy new or rechrome?

[e5j]

Greetings Earthlings..

I'm 80% done with rebuilding a 72 K5 that I bought in horrible shape. So bad that it was 50-50 whether to save or scrap. My friends thought I was nuts.

I am at the point where the side window glass and wing windows need to be replaced. I have the original wing windows but they have some surface rust.

Parts companies like Brother's Trucks and Mane's have factory replacement wing windows for $150-180 a piece. I have the originals still.

I have never done this before so I seek experienced folks here. Does it make more sense to sand and rechrome (or powder coat) the wing windows I have or buy new ones?
