1998 SC400 MAF bolt part number?
So, I lost one of the bolts for the MAF. It's slightly an odd bolt in that it has a centering collar extending about half way down the bolt. Anyone got a part number for that?
I also seem to have lost one of the intake manifold bolts, but I did find a part number for that: 90148-80026
I might find them when I've got better light, but I'm preparing for if I can't. I'm assuming they've been caught by the plastic under-tray, but who knows where if it bounced at all.

Well, that bolt doesn't appear to the unique to this one car. It's the same as the SC300 (going by the drawings in my shop manual that covers both.) It's probably fairly common across Lexus and Toyota cars/trucks/suv's that use that same MAF.
On the other hand, I see quite a few SC400 and 300's on my daily commute in to Seattle. Maybe I should start taking pictures and put up an "SC's in the wild" thread. Not like I'm doing anything else for the hour of stop&go driving... each way.

You might be in luck then. Seattle is the one area in the NW I see lots of SCs for sale, so there's bound to be a few wrecked ones...
I just checked what I've got and it turns out I replaced all the MAF bolts with nicer hex head ones. I forgot I had replaced them all, but I do remember that old, soft metal being pretty badly stripped by POs. Replace 'em all and you'll soon be like me, forgetting they aren't original.

Well, it's not like the MAF needs to be torqued down, it just needs to be held in place and loosely seal the cold(ish) air pipe. It's not like there's real pressure (or vacuum) that it has to seal. So I shouldn't be particularly worried about stripping the bolt as long as I use an appropriately sized socket on it and not pliers or vice grips. By that rationale I should be able to use just about any appropriately sized bolt, but it's quite possible there's a reason they used the collared bolt, possibly to keep people from over-tightening and breaking the plastic MAF housing.
I stopped at a local large hardware store and picked up a magnet on a stick this morning, hopefully I'll be able to find it by poking that around over the under-engine tray.
