does the b series trucks share a platform with anything before they were rangers. i was looking at a ram d50 today and it looks exactly the same, like the fenders, bed and interier. if so then the mitsu mighty max is the same. i also heared that it was the same as a izuzu, not sure which one.

 

The Ram D50 is a Mitsubishi. The Ford Courier and the Mazda shared platforms for many years, but this stopped in the mid 80's. I'm not aware of anything that shares with your p/u.
