engine problem 87 Bronco 2

I had a problem and need to replace the 2.9l in my Bronco but can't find one here. was wondering if anyone had replaced with a different engine and trans that would be easier to find than a 2.9l

I just sold my BII with the 2.8 to a buddy who wants to rebuild it as a replacement for his 2.9. There's nothing wrong with the 2.9-he just wants to rebuild a 2.8...go fig. Private Message me if you'd like to inquire about his other engine. (He had a few BII's when I dropped mine off to him.)
