Recommendations for a workshop in Melbourne

I've just moved back to Melb and looking for a shop to fit some stuff for me. If you have any recommendations for a trusty, reliable, decently priced bloke please share. I'm located on south-east, so hopefully on my side somewhere.

Looking to get 4.625:1 diff gears fitted and 43% or 63% transfer reduction (hopefully LoveKe70 still has a few spare 63s floating around)

Will probably get the diff gears from here:

(sold by www.the4WDshed.com)

$900 for the pair seems good...... I wonder if they are much different than at Marks4WD.com which sell them for $1390 a pair. Any ideas?

You could give Paul a buzz at Outback 4WD in Bayswater,
see what he has to say, mention John from the forum if you want
