Speedo Trip Resetting

[mac5777]

Hi guys, I purchased these on E-Bay years ago for my S3 Elan and was told that the reason they did not fit was, they are for the +2s. I was about to list them. I think I paid about $15.00 each. When the first one did not work, I got the 2nd one that was designed to fit a hole in the dash rather than being bolted to the dash. I have no need for them so if anyone see a fit, make an offer, any offer will do.
You push in on the knob and turn to re-set.
