Hi guys I was wondering if you could please lend some advice.
I have a 1991 JDM Toyota Soarer uzz31 V8 that just had major service done.
Same 1uzfe engine as LS400, SC400 in USA as you likely know.
It seems someone online in the parts industry has mixed up numbers, aftermarket sellers have parts numbers wrong.
As you can see in attached images, the screw holes for the parts are different sizes. The USA version is missing locator rings.
JDM has small holes and bolts, USA has larger holes and bolts. USA parts seemingly will not fit on a JDM version of the engine.
Our local car store "supercheap australia" sourced me Bosch GD830 and 831.
They are listed as "to fit 1uzfe engine - Toyota/Lexus". The holes are too large as I just found out.
The screws of the USA items are too large to fit the JDM engine.
I can bolt the stuff up using the JDM screws but I fear the distributors will eventually vibrate and wiggle out of place, causing issues.


I'm looking for rotors+caps with the small holes in Australia, or able to be shipped to Australia.
Anyone with info, please chime in. I appreciate it

- 1910250020 is part number for JDM rotors.
- 1910150020 is part number for JDM distributor caps.
- Online, sellers are mixing these up with larger holed USA parts seemingly.
