GLOOPY Posted January 8, 2023 Share Posted January 8, 2023 Good AfternoonI need to replace the 1/2" diameter lower rear damper bolts on my 2019 420R. I've spent hours looking for the exact correct spec of these on the internet without success. Either the overall length is not available, or the grip length or thread length. Even tried aircraft spares suppliers.Could anyone suggest a supplier for these and the Schnorr washers please?Many thanksDavid Link to comment Share on other sites More sharing options...

Doc007 Posted January 8, 2023 Share Posted January 8, 2023 Make sure when you're putting the new bolts in that the hole on the DeDion lines up as it's easy to cross thread. Link to comment Share on other sites More sharing options...
Wrightpayne Posted January 9, 2023 Share Posted January 9, 2023 The excerpt from the guide doesn't show the thread size - my '98 S3 build manual says 1/2" UNF. Also 10.9 is a metric tensile strength specification - there is an imperial equivalent (I'll check this out and report back later) Link to comment Share on other sites More sharing options...
GLOOPY Posted January 9, 2023 Author Share Posted January 9, 2023 Thanks to everyone for their help, much appreciated. The point about being careful on replacement is a good one as the existing bolts had been damaged by incorrect installation, Managed to save the captive threads in the hub though.Chris at Redline has come up trumps.Thanks againDavid Link to comment Share on other sites More sharing options...
