Yes left everything in. The shock mounts were far enough away if you weld one piece let it cool completely then the other side.markmitch said:
They brought the lower control arms 1.5" above the floor. Didn't have to lift the body as high to clear.dcsleeper said:
Finishing up on the air cleaner assembly, still need the end piece. The hardest part was making sure I could get to everything I needed to without taking it off. Like oil dipsticks and brake reservoir and still shut the hood. I used a air filter from the Tahoe. Got lucky again the Tahoe elbow with temp sensor and air filter service indicator along with a silicon 90 worked perfect. I could have made it easier by using a K&N filter but I wont put that crap filter on anything. No I'm not concerned about not having cold air to it.
Now for oil fill, possible passenger side valve cover?

Thanks. The reason Im not worried is when I did the lift and had the 4.3. I used the stock air box but took the cold air duct of because no way would have fit. It sucked under hood air all summer and winter. No issues. Hope your not right this time.sixsix said:

I've had them in the past and always had some light dust in the air box and hoses after the filter. I thought it was me not getting it set in just right. For 2 filters the same size and 1 flows more air it has to have larger space in the filter material to do that or more pleats. In this video the K&N does not have more pleats or is any larger than the rest. So it must have larger space and that can't trap small dirt particles.
I did look at a replacement K&N and its is smaller than paper filters. About 1.5 in height and 1/2" in diameter for normal duty filters. Heavy duty paper are 1.25" larger in diameter.

Moving along. Maybe get it started today. I want see if I need to fix anything up to this point before I button it up. Air cleaner housing is done except paint. Tahoe Rad hoses are in, only had to trim the upper. Need to finish up a little wiring for the fans. Exhaust is almost in but only to the mufflers. If it starts and runs then Start on the Transfer case wiring. I have it done just route it in the van and find a place for the switch.

The 246Transfercase is wired up. All tucked away and read mostly ready. Have 2wd hi, 4wd hi, and 4auto. Just 1 wire Im not sure about. Some how the TCCM needs to know that the trans in in Neutral. I have a green wire f15 from the orange TCCM plug. I believe thats the one but cant confirm it. If anyone knows I sure would be appreciate it.
Last pic is where I thinking about putting the switch. What do you think?

You're welcome... I made it more elaborate than is absolutely required - I added a second cross piece to the surrounding dash bezel because I wanted it to look just so... But you could just block off the lower part of the duct and simply replace the lower vent with the switch....
Good luck!
Good luck!
Oh you used the switch as the filler where the lower vent was. No wonder I couldn't find a blank for the vent was today at the pnp.gavio said:
For your Tcase to go into 4low does the trans need to be put into Neutral? If so how did you wire that? That is the only wire I need to do. But I can not find a wire diagram for a 99 Tahoe. I know its a green wire F15 on the Tccm to the pnp switch. I dont know if the wire is power, signal or completing a ground. Would you know?

Yes, it did.... I don't have the 233 any more (I switched to a 231), but back when I installed the electronic shift, I did a writeup, and it talks about that very thing...

I'm pretty sure you need to do the exact same thing to hook up the 236
