Spacers between the lower control arm bushings for 92 SC400

[DJ420a]

Is there anywhere online I can find these? I think the actual bushings are fine, but there are some type of spacers on each side of the bushings that have broken down or just broke apart.

Is there a site or something I can get these from or might anyone know the part number to these? I checked www.lexus-parts.com and I couldnt find it.

TIA
