I am looking at a super clean '89 auto extended cab truck with a bad 2.6 motor that I can get for $300, but it has the unusual size bellhousing. I think it's the bigger version (16" measured between the lower dowel pins?) as opposed to the smaller (12.5?). Any info on these engines would be much appreciated. I used to have a '92 with a FI 2.6 5 speed and loved it!!
