When installing the universal joint on the trans output-shaft, does the dimple on the B-7095 washer go towards the transmission? What is its purpose?

Sounds as if you have an aftermarket washer. The very small tab has no purpose . Usually the washer is not flat but crowned slightly. The high part of the crown gets the bolt head, I would add a lockwasher also.

Yes, aftermarket from Third Gen. So that being said, should I install it with the tab/dimple towards the trans like the picture shows?

Many authentic washers did in fact have that tab. The washer is actually a Belleville washer. The convex side is positioned against the bolt. And, as has been previously stated, a spilt type lock washer should be installed as was authentically done.

The washer has to lay flat against the U-joint so install the dimple toward the head of the bolt and use a lockwasher.

Thanks everyone. I installed the washer with the dimple towards the bolt head using the supplied lock washer and a couple of drops of blue loctite. I actually have two of the aftermarket bolt/washer kits. The one from Third Gen, and another from Mac's. When I put a Starret machinist square across the washers they are both dead flat on both sides..... defiantly not Belleville washers like the original.

I don’t know, but I am thinking the tab is intended to simulate the Belleville spring of the original washer, so it would go towards the u-joint. The tab would be deflected when the bolt is tightened, similar to the Belleville washer. I would like to hear from the supplier which is the correct orientation of the replacement part.

Well that just figures, I just got off the phone with Michael Driskell at Third Gen. The dimple goes towards the transmission. He said it makes the washer act like a convex washer. He said he could get the convex washers, but they are $25 each. Luckily, I haven't installed the torque tube yet so it's an easy fix.

The tab, as Driskell told you, does in fact go towards the transmission.
