Alright, I've tried to find a definative answer but I mostly see alot of doubts. I have a 90 ls400 and the front seats are trashed, I was wondering for me and everyone else that wonders if the seats from 90-00 are interchangeable as in atleast bolt up. The wiring issue wouldnt be a problem as I would be able to find diagrams for like power seats or what not, not really for srs or the seat belt indicator. Just wondering if they would bolt up or need slight modifications. There are many 96-00 around me but not alot of 90-94. Sorry to bring up such a old topic

why not try and put the doubts to rest? maybe do a rough measurement on a 95-up and see how close it is!

from my recollection, likely only 3 of the 4 holes line up but it's something that wasn't explored further as you found.

I don't know the exact year, but sometime around 97 or 98 they introduced side airbags into the seats themselves. I know my 98 has them. That may add complexity.

But that's all I know on the subject. Good luck!

I had side airbags on my 97 which was the year they introduced it, but the OP doesn't really care about that as stated.

Yea I see. I was just seeing if anyone has done it. The side airbags thing doesnt bother me. As long as they mount up I'm good

It could be dangerous to use seats that have airbags in them. Manual says they have to be properly disconnected before scrapping.

for what it is worth, I pulled one out of a 99 LS and bolted it in my 95-97 ls but could not plug it in, because of the WIRING, plugs were a match..

Ah I see, but it bolted it up right? In that case I wonder if people swap mk2 seats on to mk1

​​​​​​They don't fit. I just bought one from corbeau had to send it back and tell them to update their website cuz it was listed for 90 to 95

From what I understand pretty much nothing is compatible with LS400 my buddy with a GS300. My buddy with a GS400 and my buddy with an IS300 have all measured and given me their dimensions and none of them match the only one that's close is IS300 but no go

I figure that the actual seat frame does not bolt into the '90-'94 original seat frame bolt holes, but has anyone considered trying to take the seat bottom cushion frame and seat backrest frame off of the '95-'00 Lexus LS400 to see if it is mountable onto the seat rail frame of the '90-'94 LS400?

I have a '92 Previa LE RWD and someone on the Facebook Previa Group posted retrofitted Audi seats in his Previa 5-speed manual on the original Previa seat frame.





From the post, the owner pulled the backrest cushion over the Previa's backrest frame. And for the seat bottom cushion he cut the Audi's seat bottom frame in order to bolt straight onto the original seat rail frame.

Here is the link to the thread (Post #13) that has the 95+ LS400 passenger seat in a '93 LS400 with only 3 bolts lining up with the bolt holes in the '93 LS400's original mounting bolt holes.

It's a nice fit and looks good, but won't match the back seat stitching/design.
