west Australian Mod plates

i bought a 2008 gu patrol ute that has a mod plate. im unsure as what the plate is referencing as it only gives a code (xxj1xx)
anyone have an idea ????

Could be anything??

what modifications have been done to the car? Long Range Tank? remove the rear seats? Bigger lift? Cut down? Engine Conversion? can you post a pic of the mod plate

this is a photo of the plate.... hope someone can tell me what its a mod for.
the pootrol is standard as far as i can tell....so whatever was done has been un-done, i think...thats why id like to find out what the plate was/is for.

call TL engineering they build bodies and trays in perth, quote their number. they do a lot of mods for the mining industry!

thanks Stropp.....pretty obvious now you said it...lol

as a follow up per Stropp's advice..... the mod codes:"xx" is how they start.....the "xx" at the end stops anyone adding on anything.
so the "j1" stands for body modification....in this case a tray built for a cab chassis ute.

Lol its just for the tray.
