Crawl Case Transfer Case gasket question
In the TG directions for the dual case build it says to pick the gasket that best fits your cases. Well, I have a photo here of the only one that fits, but it seems that oil flow between the two would be a little restricted due to the fact that the holes are covered.
This is the gasket that fits, if you take a look at the gasket right below the main shaft bearing you can see that is the only hole in the gasket that would allow oil flow, besides what comes through the bearings:

In this photo, without the gasket, you can see that there are three main holes. There is one above and below the main bearing shaft and one above the counter shaft bearing as well:

If you take a look at the adapter, it seems that there is a cut out by the counter shaft bearing for oil (bottom bearing on the right side of it). If you take a look at the photo with the gasket and you notice that oil hole is blocked by it. The other two holes on the photo without the gasket seem like they would be irrelevant because the adapter plate "blocks" them.

Any ideas/thoughts on this? I don't want to mate them together until I get this figured out. Thanks for any help/input.

Here is what I ended up doing.

I talked to TG and they were of no help, except that they said it was a stock gasket. Yes, it is, but that is not a stock setup. With that said, I don't think that you can simply apply that train of thought. I simply cut the gasket to allow better flow of oil between the cases. It may not have been necessary, but it just seems like a good idea.

It wasn't suggested in the installation guide when that part came up, so I just used the gaskets. I'll cross my fingers on no leaks. If so, then I'll be fixing them later, but I'm not taking it all apart now. I have both cases fully built and ready to go. If I take them apart later I will upgrade the output shaft to 23 spline and FIPG the mating surfaces.

Using a tap to clean up threads on tcase mount bolt holes
1884 4runner 22r
I have a dual case built and I picked up a case from IL (im in WA) that I used for the crawl box. I was putting the tcase mounts on today and the crawl box mount bolt holes were packed with dirt and the threads are a little beat up inside and a bolt isn't wanting to willingly go in. I was thinking the best shot would be to chase it with a tap. Anyone happen to know the proper size? I have attempted to clean the holes for about 25 minutes, no luck with the bolts wanting to easily to in. Thanks for any input/help.

The threads where you mount the tcase mount to the case?
Tcase mounts are short M10x1.25 if I recall correctly. I have a bolt sizer on the wall for these kinda situations.
I can check on one in the floor tonight if you don't know by then.
