Hi Chris
FYI there are two different types of the damper for the manual rack, I was lucky enough to buy a bundle of parts which included two new ones (sorry not for sale as I need one for the car and will keep the other for a spare just in case). I did spend some time before that looking for them without success, but was only aware of the one with the rubber outer (which had completely perished on the one on the car. The other type has a metal outer which is more like a conventional shocker and probably would be a bit more resilient to the heat from the exhaust.
Even if you do not replace it, I suggest you wrap the exhaust to try to keep the temp down around the rack gaiter which does go brittle with heat after a time, again mine was pretty poor when I took it off.
The two I have are
WAY ASSAUTO pn not easily read, but has Lancia p/n on it
Stabilus pn 01 20 164 200 19/7X where X is unreadable, but may be 9 <-- This has metal casing unlike the Way one
