Hi Syed, If you have a damaged a Series 100 car drive flange we can supply new (actually for pre and post 100 CAVs) drive flanges. My understanding is that the drive flanges are bespoke parts and Series 100 parts are no longer being made as spares by the factory.
Since we're doing the complete job here it's possible to accomodate original six pin wheels as well, very cool.
If the drive flange measures true, has no obvious nics or cracks, hasn't been crashed then it's probably OK. What's going on that makes you suspicious of the drive flange?
Cheers
