If the museum that currently holds a Lavi prototype states it has that radar, I’m pretty sure it can be used as a primary source. See if you can find anywhere online where the museum specifically states that it uses the radar and that would be the best kind of source you can get.
However the sources for the Lavi suggestion here on the forums state it used the Elta EL/M-2035 radar.
Tbf, the post does have a lot of misinformation, but yea, it only carried the 2035. It’s easy to mix up with the 2032, as back then it was made for the Lavi (but as far as I know, it wasn’t mounted). It should be noted however that it had the possibility to fire ARH missiles.
Apparently some sources state the PL-8B also has a big engine upgrade, making it a lot faster than the PL-8, which might explain why gaijin doesn’t want to add it.
Lavi is a must if Israel’s going to have any chance of becoming a faction people actually want to play. Reskins and variants are fine and all but a domestic jet, even with a limited armament, would help a lot
