Albanian language derives from R-Z2103, Central Balkan EBA and MBA locals. Ulanci carried R-CTS7556, and Ulanci group had some direct parallels to Paracin and Brnjica groups. It's obvious Central Balkans became a refugium for R-Z2103 already based on N.Macedonian results.
The strongest Albanian cluster is R-Z2705, it is several times more numerous than any other Late Antiquity/Early Medieval cluster in Albanians. Lumping E-V13 and J-L283 clusters with TMRCA of 3000-4000 years together is ridiculous, as these could have had completely different histories.
Southern Albania also was run by Z2103, it was the Brygian territory, and the Matt painted pottery, which also influenced Ulanci originates there.
LBA saw arrival of some Gava people (before they would form the Psenicevo and related cultures in EIA), then the Psenicevo itself. Latest was the arrival of Illyrians from the West, who have nothing to do with the original Dardanians.
Basically Illyrians are as Dardanian as British are derived of the Bretons. But they formed the ruling class and according to reports even ruled the indigenous Dardanians with an iron fist.
The area also sees remnants of non-Illyrian, non-Thracian speakers surviving even in 2nd century AD. These may or may not have been related to Albanians, but there were obviously various survivors in the Central Balkans.
There is a small chance Albanian derives of some indigenous remnants in Albania, but this is made almost impossible by the linguistic and historical arguments (Matzinger etc.).
