Discussion thread: http://www.oldschool...hp?f=18&t=27265I bought my car around 10 months ago. Since then I've done shed loads of boring but important shit to it. One really bad thing I did was install a VLSD. To get things up to speed this is how it went:Firstly, I would recommend against anyone doing what I've done. In short, I've ended out with a VLSD in my 240z for $923. Had I known it would cost this much I would've put a _real_ LSD in.Tony(?) from Steelie Gears told me as much when I'd phoned him for help, but I'd already bought the diff and it was too late to turn back.My main goal was to get my car back on the road after the spider gears in my open diff gave up. Then I saw a longnose r180 VLSD on TradeMe for $350 so figured I'd grab it as an upgrade. It should be stronger than my original 2-spider open r180, and it's LSD-ish.Anyhow, I pulled the input flange of my old diff and bolted it up to the new diff with no worries. The major hurdle was converting the output flanges to uni-joint ones. Basically I got the VLSD shafts cut off their CV cups, and welded them to the uni-flanges from my old diff.First I took them to Taylor Automotive in Newmarket who totally wasted my time. They cut the shafts off and then gave up without calling me.So in the end I got Colin at Gillespie Engineering in Penrose to do the machine work. He's was a good dude and happy to help. They did an excellent job, see pics. It only took around 3 days but it cost me way more than I'd hoped; $573. But looking at their work I can see why it cost that much.
