406 diff question

[amazon69]

Hi,

I need a diff pinion flange for my 406, which I imagine is a hard to find part, but I believe the car has a salisbury axle, which is not so uncommon... I thought maybe the flange would be a common spline count/size shared with other vehicles. Does anyone have any tips or advice here to help me find a suitable flange?

Also, did the 406 have a prop centre bearing? I can't see any pics of it in the various manuals.

Thanks a lot.

Dave
