Is there any cross compatibility between any other Lexus model in regards to the top piece of the battery tie down assembly? The piece that goes across the battery. Can only find rusty used parts for $100, new from dealer and lexuspartsnow.com are discontinued.
From what I can gather the LS400 OEM p/n is 74404-50020

 

Part is LS400 specific. Toss the thing in Evapo-Rust for 2 days it will come out rust free. Then paint. Make sure you're battery is not leaking acid.

Might be available here but I doubt it

Thanks! Got the car and its missing, so the battery is just sitting in the tray free to float around.

 

I'm sure you've seen this

Not much choice out there get it before someone else does.

 

you know i didn't actually! They also have the rusty top piece for $110+ after shipping, but this i’ll take. Thank you! Purchased it.

 

It's not good to have the battery unsecured. Safety is one concern. Another is vibration and shock isn't good for battery internals.

Battery Hold Down: P/N 74404-50020, NLA. Looks like it's still available here: https://www.amayama.com/en/part/toyota/7440450020

Confirm with Lexus that the available parts are in fact available.

Thank you!

Yeah, I've hated it ever since I got the car. I verified with my local Lexus dealership on everything, even got a j-hook, and they confirmed the hold down is NLA. I snagged the complete kit that LeX2K linked above, looked to be in pretty good shape.

 

I buy a pile of parts from Amayama when they say >1 can be supplied quantity unknown that usually means the part is NLA.

 

Lexuspartsnow said "in stock" for it, and voided my order an hour later. Is Amayama quantity pretty accurate in your experience?

 

Typical.
If Amayama shows actual stock (not just >1) then I've always received the part.

 

I just bought a pile of parts. All from the Japan warehouse.

A quarter were in stock. More than half were ordered and arrived within a week. A couple were NLA and were canceled (hoses mostly). And a couple needed special orders (10-30d delay).

All of them said >1.

 

>1 is hit and miss, just remember if you buy a bunch of items and all end up being NLA except something low cost you still pay shipping. Meaning shipping could be much higher than the item itself.

You'd think in the era of computers they could figure out inventory.

 

Bell Lexus doesn't show it as discontinued- https://parts.belllexusnorthscottsda...440450020.html
You might call them to verify.
