ok. there is a difference in blocks on 308
if the engine is upto and including VL 308 then its a trimatic stud pattern.
if the engine is post VL ie VN onwards then its a turbo stud pattern. if you are able to find out what the engine is out of then you will know what stud pattern the bellhousing is....
just saw the pic. looks like turbo stud pattern to me....
(i know this cause i just pulled a 308 out of a VN at work on thursday)
