The forum search function isn't too good.
I use google with 'site:'
site:bikeforums.net/classic-vintage/ sales stronglight arm
Link
Then you can click Tools and select a custom range of Time (or past week, month, year)
The short text thumbnails in the results are helpful.
Doing this as an Image Search can be useful too.

Searching just that one thread:
site:https:// www .bikeforums .net/classic-vintage/ 1136042-iso-trade-thread-part-5-a .html stronglight
(..brain dead forum software keeps converting this text into a link. spaces added to show this as text.)
returns one result.

for example (and I need to put rm -rf in quotes so google ignores the dash.)
