Sweet, those ends should be the 3/4 ton GM style ones, very stout.
But, the rubber boots on them just sit down over the casting and have no snap ring seal, in our climate the salt water gets in there like nobodies business.
4x4Labs supplies 80 style ends that are sealed like the OE ones, but there is obviously no place for the relay rod, hence the new custom, double forward hole, arms.
To be difficult, I got a set of tie rod ends from Toyota to verify that they could be run, the one mistake I made was ordering the tie and relay ends when I actually needed 2 left and 2 right tie rod ends (the relay rod ends are a different size)
The taper on the 80 ends is actually smaller than the taper on the 60 ends, so 4x4Labs supplies a cone spacer for the pitman arm. The Toyota ends also do not come with jam nuts, but I was able to source those from Marlin @ $1 a piece. The 80 ends that 4x4Labs and Marlin sell are the same brand, come with jam nuts and are good quality, I just wanted to be a Toyota bigot and figure out how to run the OE 80 ends, when these wear out I will try a set of the 4x4Lab ends since they say they are excellent quality and I trust their opinion.
John, they are sending the kit to me for a test, should be here soon!
