Forgot to add 3.15 lsd and removable steering wheel.

Anyway a set back and then some progress. Got the spacers in from VAC for this job it is the M50 spacers and not the M54 so those will go back. I did a test fit and thought I would be good to go. Threaded in the inner bolt and just put in the outer to hold up the power steering pump. Pulleys line up so lets bolt it in. I can't get the outer bolt to go in. I think there might be dirt and crap in there so I put my ratchet on there and it still wont go. I then realize that this hole is threaded. On the original housing it is not. No worries there I will just get a metric bolt that is fully threaded. My plan is to thread through to the nut on the power steering bracket. That wont work either because unlike the original housing tha hole does not go all the way through. You can see a mark where it would but it is not there. So I slowly threaded the bolt into the metal and foced the hole open and then cleaned it with a Dremel Tool.

Here are the spacers from VAC and the inner and outer bolts. Short one thread in both housings.

Test fitting and and finding another issue to deal with.

There is no hole here on the Euro housing so I have to take the whole thing out and solve this.

Since all of the housing bolts are different sizes you can label or do this. Not my idea but worked really well. Out of the housing into the cardboard. You don't mix up or lose. Washes stay right with the bolts.

So I am now going to drill out the threads on the housing. The holes are different sizes on the two housings but the bolt threads are the same. I know it makes no sense but trust me, there is about a mm difference. Since the inner is threaded on both units it hold the pump/pulley out in place but I wanted the outer hole to be as small as possible. I grabbed a handful of drill bits and found the first one that got resistance from the threads. I ran it through. Went up one size and the bolt went through. The nice thing is that the center of the housing is where the hole is the tightest so it should not stress.

So back to this picture. Notice the space between the bracket and the oil filter housing. A few washers should do it.

Outer bolt is now threaded into the nut that is contained on the rear power steering bracket, just like the original housing. Lines on tommorow and test for leaks.
