K100 cab suspension (looking for)

Hi, got a Australian K100E I'd like to fit a US rear cab suspension too, without spending $3000.

Looking for the tunnel cross bar, cab mate assembly, and associated mounting brackets.

Or advice of where to find one form a probable wreckers or someone's paddock.

I've been shipping a few parts over so a little familiar with exporting from ports.

Any assistance or direction welcome.
