Strut Inserts, 5 stud struts need identifying and adjustment Options

[Philw]

Hello again from the UK, I now have my '74 2:0 litre back from having the hell hole and associated problems repaired and am about to embark on the reassmbly and return to the road after 8 long years.... On my long list of "to do's" is the fact that the 5 stud front set up that I swapped to (this was the original reason for the 914 being taken off the road 8 years ago).... is not sitting quite right in that there is more threaded strut showing above the cup and lock nut in the luggage compartment than there was with the "old" 914 set up. It is so bad that the lid can't close properly as the tips of the strut make contact with the bonnet. I was told the struts were from a '73 911S but then do they "all say that"??!!! the rotor is vented and the strut is red. If you guys are still with me my questions are as follows:

Can the strut be adjusted so the threaded section is wound into the strut allowing the proper clearance?

If not do I need to swap the insert for a 914 insert?

How can I identify which model of 911 the strut assembly is from?

Thanks in advance for your help, if neccesary I'll take some pictures to help. I am sure I'll be back along lots more with questions as I try to get the old Texan girl rolling again....

Phil
