Assuming your’re on about an anglia and not the Micra, last time i did one they were held on by two long nuts and bolts. Nothing captive at all. The difficult bit can be the shock link, which can turn and turn if the rubber has parted company with the metal.
My last Anglia must have had conveniently rusted-in bolts, don’t remember having to find the other end of the bolt before!
Upper link separated with some persuasion from a screw-down joint separator. Offered up the replacement recon damper that I bought from the autojumble at last year’s AGM, labelled 105E, and it doesn’t fit! The arms bend the wrong way.
Buyer beware! (Or at least take your parts book with you when buying).
