If u remove the Slavic admixture Albanians received during Middle Age then they would have been identical to the Bronze Age Dalmatian (he even carried a Y-DNA common only among modern Northern Albanians), the Iron Age Dalmatian looks like he mixed with Latins of some sort. He got extra WHG admixture something which the Bronze Age sample lacked.
I think, even Illyrians from Albania and inland will be no different from the Dalmatians, maybe slightly more West_Asian and less WHG than that Iron Age sample.
You have no idea how wrong you are. Firstly Iron Age Illyrian is more Northern shifted because she is Iapodian (I believe even by archaeological location), nothing to do with "Latins", who barely existed at the time and were not migrating to Illyrian areas. Iapodes have received additional Urnfield admixture in LBA/EIA. These Urnfield people would have been Bell-Beaker-like.
I actually think some linguistic evidence might point to Illyrian connection, but here's something about autosomal DNA.

Modelling the Slavs as average of Sungir6 and AV2, assuming Albanians have 25 % of Slavic autosomal admix. (Slav-Sungir6.AV2,27.93,46.57,12.08,4.33,4.39,0.61,0.25,0.00,2.08,0.99,0.29,0.48,0.00)

Who are SZ40 and SZ43??
SZ40 Langobard looks like a Romanized Thracian/Mysian, away from Illyrians. Female.

SZ19 is a Thracian, it's crazy how Thracian she is considering IA Thracian sample was more Southern shifted yet SZ19 is much much closer to Thracian than to Myceneans or anyone else.

The reason modern Spaniards cluster with Illyrians is that Illyrians were a mixture of Bell Beaker and Neolithic (Dalmatian MBA were 60 % Central Euro Bell Beaker + 40 Dalmatian Cardial EEF) elements whereas Thracians and Greeks were Yamnaya + Neolithics (in various proportions, with Getae having the most, Myceneans least of Yamnaya). And BB and Yamnaya were not quite alike. Also some differences in Neolithic elements, but the main difference was along the BB-Yamnaya cline.
Scy192 from Moldova from 300 BC is also way closer to a proto-Albanian candidate than Illyrians:

These "Scythians" are surely
100 % Getae, look at their distance to Early IA Thraco-Cimmerian from the similar area. Superficial partial similarity to proto-Illyrians is due to more Steppe admixture, but in their case it is not Bell Beaker derived like in Illyrians, rather Yamnaya.
So having N.Albanians without the 25 % of Slavic autosomal makes them
Thracians. And Albanians (this sample for sure)
cannot be modelled as Illyrian + little Slavic because the distances are too great.

You see these combinations with Illyrians don't work with only 12-14 % of Slavic admixture!!
ofc Albanians have some Slavic autosomal influence, they have more Baltic in K13 than any Paleo-Balkan population. And way more than Illyrians.
Well we see there were a bunch of romanized Thracians among the Szolad samples, likely heavy with E-V13. So looking at these results it seems some of these V13's positioned in Illyrian areas today might actually be Romans of Thracian origins. I think it is quite possible even that Illyrians had no more than 5-10 % of V13, and were like 50 % J-L283 and completely opposite with the Thracians (including Northern Thracians/Dacians/Getae). Albanians do have significant Y-DNA Illyrian ancestry but it looks like they have heavy Thracian autosomal admixture.
