3.6 Turbo Speedlines

[ssute]

What are genuine speedlines worth. I have a set of unrestored wheels with good tyres.
The wheels have some corrosion around the bolt holes only, otherwise in great condition. The rim has Speedline for porsche
10j part no 965.362.140. offset 61
8j part no 965.362.136. offset 52
Thanks for your help.
