[Fot] Koni Bump Rubber and Rebuilding...

Hi Brad,
I did get your original message, excuse me for not writing then.
I don't thing there is any need for the bumpers or cover.  I removed them from the Spax on my TR3.  It's a good idea to check the shock travel.  You can not see the travel with the covers in place.
Put a zip tie on the shock shaft and make sure the shock doesn't bottom out.  It's good to know the suspension travel.  The zip tie on my shocks has been pushed close to bottoming out.  The Spax bumper would be contacted and I might never know it.  If the zip tie goes missing or gets damaged, you know there is a problem with the shock bottoming and you can make an adjustment.   I added spacers to extend the bottom shock mount for clearance.  You can check the travel in your garage with the springs removed.  You might find enough clearance to reinstall the bumpers.
Leave the zip tie in place for continued monitoring.
