Hi,
your wagon looks mint but the photo you posted is a bit small, a larger pic would be nice.
I don't know of any places in Mackay that would make a diff for you, but if you can't find any there is plenty down south that specialise in shortening diffs. Just have a look in any Street Machine magazine and take your pick.
Have you thought about running a borgwarner diff. I have a VS commodore SS diff in my HK monaro. Can't remember widths but it was real close. I changed the gears to 3.7's and have run 11.60's with a 307 and 100 gas with no worries.
