What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I guess it's hard to tell by the pic, but the area in the circle looked rough and not uniform so I thought a piece had chipped off in that gap area. It's been awhile since mine was removed so I forgot exactly what it looked like.

I was going to suggest filing it but looks like you got it figured out.

Finally got around to doing some needed items. Had to replace fuel lines from filter to tank. Since had to drop tank also replaced fuel pump (kept old one as backup). If this fuel pump goes then I will be cutting the floor and making a little door. While tank was off replaced rusted brake lines (just used OEM line). Paid local shop to do lines ....was not about to do that laying on my back in the front yard. Did AC Delco plugs and wires. Also did the intermediate steering shaft and bushing...laying under dash so might as well do both. Damn my back is getting old.

Gotcha. No, that’s both what the keyed/stepped portion looks like and the shadowing from the lighting. There might be some overspray from copper anti-seize in that area as well, adding to that chipped look.

Nice catch though, I can see now from the photo why it would look that way. I’m looking at it in person scratching my head and wondering: “Did I miss something here?”.

How much of a pain were those fuel lines? I’ve done brake lines, and will never do them again.
Maybe with the right double bubble flair tool and the new style flexible lines it wouldn’t be so bad, but the old hard lines with zero give were a nightmare. The new ones you can damn near bend by hand, whereas the old ones wouldn’t budge using a conduit bender. Then all of a sudden 170° with a hairline crack. Or it would blow out a foot from the location you repaired.

I tried repairing my hard line that feeds into my steel braided brake line on my ds rear caliper(03 Tahoe). Someone used a compression fitting to repair it--it was leaking like a mf'er. Bought a double bubble flaring tool from HF. Very long story short--I bought a length of flexible pre-made hard line from Advance Auto. Was so much easier.

By "The new ones you can damn near bend by hand," I take it you mean nickel-copper/NiCopp/Cunifer. I started using it for every hard line about five years ago, and it's a pleasure to work with. Easy to fabricate and easy on the tooling.

Before anyone reacts with anything along the lines of "USING COPPER FOR BRAKE LINES IS DANGEROUS!!!," please educate yourself on nickel-copper/NiCopp/Cunifer, which isn't "copper." OEMs such as Volvo have been using the stuff for brake lines since the '70s.

Fuel lines were flexible braided type and brake lines were preformed type...Found local shop to do those two items for at a good labor price.

What brand black housing headlights do you have there? DEPOT from Ebay, they were around 210$. Those seemed to have been bought the most and the reviews were quite ok if I dare say good. Most other housings seem to always complain of bad beam and water intrusion.
How long have you had them? They have been on the car for 3months and have not had the fogging or water injestion issue. I was going to reseal them but was impatient and decided to swap them and see who they look and to my surprise they did not leak.
Any issues with condensation? None at all.
What’s your opinion on the light output of the HID projector compared to OEM headlights?

Original plan was to actually open the new lamps and install a proper HID projector, however I discovered a very nice replica of the HELLA E55 projector that is in the original housings done very well with a clear lens and very sharp cutoff and the hot spot is centered at the cutoff line so they are very OEM like projectors and they are DOT certified and I am not surprised given these are DEPO lamps and they are used as repairs post accidents by certified body shops.

SO I left the projectors alone only thing I did was install new bulbs and ballast on the driver side and down the road I may try LED bulbs but I know they will ruin the beam.

I love the look of the black trimmed housing on the GMT900 Escalade but am so hesitant to go with an aftermarket headlight housing…

They do look nice, I think this is a good set up for decent price to swap old aged lenses and projectors. my old housings will not adjust at all and that was enough reason for me to throw them out of the truck.

Are Koi carp? Be careful of the raccoons--they love to eat fish.

Raccoons don’t stand a chance in my backyard with a 110 lb Malamute at the ready. Besides, it’s 4’ deep and if they can’t stand up they can’t do shit. A swimming raccoon is only trying to get to where he can stand up. Also, nearly all my Koi including those new ones are around 18-20” already and growing fast so they might scare the raccoons themselves. The Koi eat anything after all, they might eyeball them.

What are the advantages over a stock replacement fob? Being able to program it yourself (if you buy the programmer)? I'm not rough on gear, so the sturdier construction wouldn't be a major draw by itself.

You can program any of the factory or aftermarket fobs without a programmer for this platform. I personally love the look and feel of the 2015 style that I was using on 3 of my trucks over the stock style for their respectable years (2002 and 2008)and since I have to replace the one I lost, I figured since they came out with the 2020 style, I’d upgrade for a few more bucks. I’m also one of those guys who does a lot of modifications to my vehicles, I never leave them stock.
