Any who needs the part number for a whip aerial to fit a Pajero (Mine is a gen 3).
It's AE 6748. I got mine from Midas, Rivonia. Approx. 150 Rond.
Throwing out the old one and routing the cable through the firewall and fitting to the head unit, was no more than 1 hour. And I have have soft as veal, man hands. Perfect reception. Try as I might i couldn't find this information on this website for some particular reason.
