sanwa exzes z antenna

[catman79]

chaps, i have a bit of a issue,
my daughter managed to break the antenna on my sanwa exzes z handset, i thought this would be easily fixed but it would appear im wrong. all the ones i have found as spare parts all list will fit exzes x, exzes z and m11. this is where it gets confusing. in the picture on the box to my exzes z the antenna is indeed the same as the x and the m11. but the handset itself is different to the picture, appears to be a newer design. the handset is approx 3 months old and was new when i got it, so this is standard equipment. anyone know where i can get one of these from? ive ordered the older style which does fit, but looks a bit crap.
can anyone help??

thanks in advance.
pictured is my handset.

this is the only one i can find, which does fit but is different. ths larger piece is part of the antenna and is not interchangeable.
