Ok so I have a stock GTi gearbox laying around and when I see through the hole where the driveshafts go into, I see 1 bar going across. This is an open diff. (Stock)
Now, the currently installed gearbox in my turboed GTi I remember seeing through the hole and seeing 2 bars (or 2 pins) across each other. Like a "cross" if you know what I mean. The guy I bought it from told me it was a GTi gearbox he brought back from the Netherlands with lsd installed in it. I'm certain it is a gti box as it has the extra hole for the brace to the block. But what about the 2 bars crossing each other?
