If so how do they have early offset wheels on them. Picture of trailing arm is above. Thanks
That is a casting number, not a part number. It does not show up on PET.

The actual PN's are:
M030: 951.331.021/022.31

but don't expect to find these stamped onto the trailing arms anywhere.

So according to PET, the trailing arm is the same for both early and late offset cars. The difference is in the hub/spindle apparently.

So for the rear, other than the torsion bars, you will need late offset axles/hubs, plus rotors and of course turbo calipers.

There will likely be some other minor things, but that is what PET shows.
