Series 1 diff questions

[Ivory 912]

Hello

I am looking for info regarding the series 1 and series 3 (e46 gen.)

Its basically impossible to find unless you have both units side by side to compare.

I wanted to check the following :

- half shaft PCD, are the bolt patterns the same ?

- width between the two half shaft flanges, are the widths of the casing the same ?

- the front mounting points, on these ears are the mounting points the same width apart ?

Thanks
