Strut top spring retainers wanted

[ChrisCar6]

Here's an old poor quality photo of a Leda strut with Hawk spring pan and beta top mount.
They are aluminium discs about 5" diameter, 3/4" thick, tapered to the outside with a hole from memory of about 1cm diameter in the middle.
Second pic of it in situ, third a diagram of cross section of top end of strut
