Hi Rémi,
from the JaPo books I got the impression that the Panzerblitz (adapted R4M rockets) was indeed much more common than the Panzerschreck (roughly an adapted Bazooka). In fact, the authors are listing the same units you mention as being equipped with the Panzerblitz (plus some additional ones). But with the Panzerschreck it seems to be a different story...
