Here's an answer I received from the eBay sellers ...So, where does one buy a bumper for a Toyota made in Japan, the dealers or junkyard?
"Thank you for getting back to us about the country of manufacture of the 1992 Toyota Pickup.
Not all Toyota Pickups for the 1992 year model was built in Japan. There are 1992 Toyota Pickups that were built in Toyota's plant in Fremont, California.
This step bumper with eBay Item Number: 352733802843 will only fit a US-built 1992 Toyota Pickup DLX with the Deluxe Level trim. It will not fit a Japan-built 1992 Toyota Pickup because they have different mounting points.
It’s our pleasure to be of service to you.
Working with you,
