@Living in the Past is there anything that you don't know about land cruisersRHD and 24 volt guessing JDM or Europe. If this wasn't at least 200 miles away would take a look at what is most likely a 40 series with a vacuum operated 4WD on a split transfer case. 24 volt and vacuum transfer case likes Australia Toyota larger 40 series market out. Even in LX models haven't seen a vacuum 4WD. All 40 series even diesels were 12 volt there. JDM would most likely be a BJ41 which Europe would be a BJ42. Think I've seen this light colored interior in both markets.
Obviously where it's at has no idea. Besides calling if an FJ40 also list it as a 6 cylinder gas engine. All short and mid wheel base diesels were four cylinder.
