Color and part numbers.
Bilstein will be a green strut. Boge Black.
I don't have the part numbers available but you can Google "Porsche Parts PDF" and go to the official site and check the 914 PDF's for your parts.
99% have Boge struts.
In some respects it is advantageous to have the Boge strut as you can buy, Bilstein, Koni, KYB and of course Boge inserts. Jim
