Which Bilstein insert do I need (1985.5 + or -)?

[wjdunham]

I need a new Bilstein insert for my front Boge strut. The car is a 1985 Carrera. I see that there are two different parts, one for cars built through March 1985, and another for all cars built after March 1985 through 1989. I can't find any photos or other details showing the difference, I suspect it is in the gland nut and how it attaches to the strut. Here's a photo of mine, hopefully someone can tell me which one it is?

Thanks!
Bill
