Hi everyone,

I'm planning on fitting an under seat fuel tank to my 85 120 ute, or even on both sides if possible. Question is, does anyone know whether it is it the Defender 90 or the Series 3 SWB type that will fit? They seem to be very different designs whereas I would have thought the seat bases in my ute would be very similar to a series 3 SWB? My understanding is that the S3 type replace the seat bases, so does this mean the Def 90 type fit inside the seat base and extend down behind the sill?

Thanks
