How to identify 911 front strut type? Options

[billh1963]

I've read a couple articles (pelican) and I don't see anything that helps identify at a glance what approximate year and type of strut you have...especially if the strut isn't original color.

I've got two sets of struts...neither are green or red. Assuming these are pre-SC, any idea on whether 911T, S, or E and strut insert type required?

I'm keeping one of the sets will sell the other. Just don't know what I have to help decide which one to keep!

Strut 1






Strut 2

First, anything pre 1969 911 should not be used on our 914's. Don't spend the money. AFAIK, split pin versus wedge happened about 1972. Another way to assume year is the width of the front hub. They generally got wider with year. Brake caliper bolt spacing is independent of year of manufacture. Generally speaking, 911E and 911S had 3.5 inch spacing starting in 1969. Early struts were originally either Boge or Koni. At some point, Bilstein entered the mix as well.

IMHO, it's worth spending the extra money on 3.5" stud spacing struts. You have many more brake options.
