I just want to confirm what I think is right.

I have 3" caliper spacing boge struts on my 914 right now. Inside them are the 914 Koni yellow struts I had in my 4 cylinder boge struts.

If I buy 3.5" caliper spacing boge struts off say a '75 and up 911 that came with boge struts will my 4 cylinder 914 Koni inserts fit?

I think they will. Am I right?

Thanks,

Kelly

The bilstein inserts (P36-112) have an O.D. of 43.7mm/1.722."
These fit the 911 Boge strut with the 3-1/2" caliper mount.
