Diff cups

[gowzy]

I recently rebuking my ball diff on my centro 4.1 however I needed to replace the left hand diff output drive , so I ordered a new one from modelsport and it was different from the old One I had in the car , this hAd a pertruding ring which stopped the play in the diff from left to right , the one from modelsport was a flush finish , my question is where can I get this diff part from which has the pertruding ring on it ?

Thanks

What was the part no of the outdrives you ordered?

the part number was AS7668 from modelsport.

I think that is the old outdrive for the imperial bearings. What you need is the newer outdrive that have the ridge. Part number 9852 is what you need but it only comes in pairs and is more expensive.
