ya I figured the p/n would suffice, the visual search took a couple tries had to get the right angle I guess. nothing even close comes up looking for "ABS clip" or related
mouser sells single pieces some other places want you to buy 500 minimum
Sorry, I was on my phone and my old eyes didn't see the Mouser part number on the package.
Thanks for posting that.

I didn't think anyone else would probably need any but I posted the part number just in case, they should be fine unless you try to R&R them like I did
to get the old one off you have to stick a small flathead in right about here and twist it while pulling on the harness connector and it will slide off
could be the other end, you should be able to see a little tab to push

Wow, that thing was nasty.
What type of oil was used throughout the engine's life, do you know?
I've only used synthetic oil in my Nissan and after 250k miles the valve train was very clean when I removed the valve covers to replace the gaskets to fix some leaks.

I'd be curious to know too, but the valley is a bit extreme since no oil actually flows over it, like in the valve cover. mine with a bore scope looks spotless inside the valve cover on the passenger side thru the oil fill, nice clean aluminum color, but I can't see in the drivers side and that's normally worse with pvc over there. my valley didn't look as bad as his, but nice red tint of varnash to it. I think the oil itself has detergent in it and it helps cool where the valley just sits there and bakes with not much air flow and almost not oil except whats thrown up from cam lobes?

I found the description on the Data Sheet to be kinda interesting (anti-rattle discs, oval "fir" trees"). Maybe the word "Christmas" is non-PC?

Pennzoil Platinum for the last 5 years and 80k miles. Prior to that it went to the dealership so ac delco I assume.

Junkyard run was a success.
Got a upper denali grille for 30 bucks. Lower was destroyed.
A new rear window switch to replace broken. All in all a good day.

Headlights are next on the list to buy. Found the mounting tab on the passenger side is busted plus they are way to sunbaked to recover

Got to work about 45 minutes early so parked and idled with the heater on and took a little nap.



Got out and realized there was a decent little puddle under the front end so my Cold Case radiator must be leaking worse than it used to.



So just ordered another one and it'll probably be here tomorrow or Wednesday at the latest.



Swap them out hopefully I don't need to buy a new fan shroud since I had to modify the old one.



See how bad it is and either clean and braze it myself or just drop it at a radiator shop and have them weld it back shut.

Baby got new shoes - Falken A/T4W Wildpeaks in 285-70-17.

...and brake calipers, brake shoes, Brembo brake rotors, and front hubs. Found out some 285/70-17s are more 285/70-17 than others. These are in the more category - a full 33" in diameter and even with the PO's ride height adjustment I had to cut some inner fender to clear them.

I'm pretty sure those things are brazed with gouda cheese at the factory. I replaced my leaky 2.5-year-old Cold Case with a Denso and haven't looked back.
