My sympathies to you Mark. I had the same annoying run around looking for KYB inserts / anything for our HPE recently. No joy, and if you want to match up a set of four, ................well there's a game!
Not convinced with quality of Spax over the years, and Billies / Konis complete sets non existent I have found.
Settled with an almost new Sachs Super Touring front pair from Mark W (Thanks), and got my rear Sachs "re inserted" so they look the same. After a coat of paint they look aftermarket. (Still some folk don't seem impressed with a pragmatic decision. What can you do eh)?
If you locate a set of performance Shocks for a HPE let me know! I won't wait up though.
Best of luck with the search.
Chas and Anne.
