Help needed - flange bolts for LSD

filip00

Hi everyone, help needed. I did the OS Giken LSD installation this weekend and all was going well until the very last moment when I was completing the installation.
As I have the sport package with VLSD, I have different flanges on the driver and passenger side - so I changed 1 flange in order to have it all fit perfectly. All was good until when I wanted to bolt the half-shaft to the flange - the screws don't fit! The problem is that the original flange just has holes and the bolt goes through and bolts to the half-axle. The new flange has threaded holes! Which means my bolts can't go through it - bolts are threaded only 3/4 way in.
I called Nissan but they don't have these bolts in stock and it seems their bolts are the same as my bolts.

Should I just go to the hardware store and buy 6 new bolts with the appropriate dimensions? Should I look for a different part number?

Please help and thanks!

Pic for reference, my bolt looks like this, and I need new ones with thread all the way through: https://neryungri.griffin24.ru/uploa...ff6c982e9.jpeg

**update, solution**

I managed to find a similar thread with right this problem and explanation:

2017 to 2009 6MT Diff Swap - Install Notes

Apparently newer model Z's have these threads reversed. It is *never* threaded on both sides, only one side needs to be threaded and this is why the bolts will always have 3/4 threads, not full.

So old Z models:
Flange hole, half-axle threaded.
Newer Z's:
Flange threaded, half-axle hole.

Happy to know the whole issue now. So I will definitely drill the thread in the halfaxle and use the new thread in the flange and that's that.
