Nylock nut size, rear flange of transfer case - also identify T-case ratio
Does anybody know the nut size for the 4 bolts on the rear flange of the t-case? Where the front of the rear propshaft bolts to? I need to order one.

Also, Can anybody help me identify the ratio in my t-case? Serial # 28D442905E

so as per Ashcroft's site that makes it a 28E which I can't find the ratio of. (I'm guessing its 1.2 but wanted to be sure). I think mine needs a 1.4 to get going a bit better.

No based on your number it's a 28D (1st 3 digits), and that would make it a 1.2.

Can't remember the size of the nuts off hand but I normally just order them from one of the normal LR parts places. Not sure if you will be able to find them locally as they are a funny thread size. Fine thread.

3/8-20 is a British Standard Fine thread and is NOT the correct size. That is the size of the bolts on the bottom of the diff.
The TC/DS bolts are 3/8-24, available at most any good hardware store, or a bag of grade 8 can be had from McMaster for pretty cheap. The bolts are 1.25" long and are pricey because of the odd size. You can buy 1.5" bolts and zip the end off, just be sure to chase the threads when you're done.
