I am upgrading from a bw 4.11 to a english axle.
I have two housing but i would like a 4.4 ratio in the rear (at least thats what i think i would like) im not sure what has at the moment actually.
Are there any suppliers in aus or should i buy new from the uk?

 
I'm not sure about Aussie suppliers, but I'm not aware of any.
There's always "Palmside" in New Zealand for Escort parts.

They often have decent used ratios/diffs as well as new CWP sets & the postage is usually cheaper than from the UK. . . although their retail prices are higher for the new stuff, but if you're happy with a good second hand CWP then Palmside might be worth a look?
I've never used them myself so can't comment on what they are like to deal with.
 
Cheers, Jason.
 

I emailed them once about some stuff I wanted to buy.  They responded promptly seeking more info, which I duly supplied, and then never heard from them again. 

Bummer. . . that's some pretty outstanding customer service.
 

Orderd some 4.4s from mst in the uk.
