engine swap M20 Swap - E21 323i Radiator Determination

[chad]

I have made the decision to use a E21 323i radiator for my M20 swap and before I order one I would like to get some feedback on which one most people use.  The early model E21 323i cars came with a radiator that has two upper mounting tabs and the lower outlet stubs out parallel to the radiator.  In addition, the early model lower radiator hose is two pieced and  has a "temp sending unit" between them.  The later E21 323i radiator is different than the early version.  The late model E21 323i radiators use a single upper mount, the lower outlet stubs out at an angle, and the lower radiator hose is one piece which deletes the "temp sender unit".

 

Contrary to the pictures I have seen on the forum, I am leaning towards the early version radiator since the lower outlet stub would, assumingly, allow for better clearance, plus using the early radiator and lower hose assembly provides a spot to plug in the electric fan wiring harness.  I have linked the two radiator for reference.

 

Any feedback or additional information for determining the correct radiator would be greatly appreciated.  Thanks.
