WTB: IRS gearbox - Either kombi/Caravelle 5 rib/6 rib or bug

Hi crew!

Baja needs a gearbox to replace my busted 3 rib. I also want taller gearing, for better fuel economy and reduced noise on the Highway.

Thus, will consider any good working IRS 5 or 6 rib bus boxes (or 3 rib with aftermarket 4.75 R&P) or a bug box.

I'm in SE-QLD, happy to drive a couple hours or pay shipping.

Thanks in advance!
Chris.

I have a few S bug/type 3 boxes and 1 single sided L bug box all in unknown condition as the vehicles were either rusted or had engine problems.
