I can lead for the Table Mesa thing. The regular guy trail is simple and I'm sure you can find your way into the nasty stuff.
For what it's worth, I switcherooed the tires on my rigs. The 95 now has the 33's, the 86 has the P235/60's and the 87 is keeping the remaining 35's from rolling anywhere. Putting the little street tires on the 86 really demonstrates how freaking quick that truck is. I'll try to remember to take it out with the GPS to see how close the speedo is now (was 25% underreporting with the 33's). It may even cooperate with a bit of a smoky burnout (pending) due mostly to how long the tires have been sitting out in the sun on the 87.
I ordered and received new O2 sensors, a new EGR vacuum motor-thingy, a new fuel filter and a couple of WIX premium oil filters for the 95 from Rock Auto. The O2's have probably never been replaced (they do get worn), my NOX emissions are way high (RyanY replaced his EGR motor/actuator-thingy; why shouldn't I?), I've never replaced my fuel filter, and I just like to have extra oil filters on hand. Having said all that, I let Jorge borrow my 95 to take on a group camping trip with his weirdo cultural, quasi church-but-not-religious-so-it's-not-about-that group to Payson for the weekend. The temp tag I put on it is good until Wednesday, so I'll try to install my new parts after I Seafoam the intake tract and putty over (temporarily) the giant vacuum leak I have at the front of my plenum at the butterfly shaft, then disconnect the actuator for another trip to emissions. Better pass.
Speaking of butterfly shafts, plenums, and now, bushings for those plenums, my brother told me the guy that made my set (bronze-aluminum alloy, hi-tech, yeah) went and died at the age of 53, which is totally uncool. So, no more of those bushings.
