Solidly made aluminium or copper/ brass rads would be better for a Morgan than the plastic tank versions. These are less likely to stand up to the vibrations a Morgan goes through.
Yours looks a good one, the black paint will also aid heat control.
My car has a plain Al rad fitted as an upgrade by a previous owner..Morgan version. The only issue was the top mount weld cracking due to side strain from misalignment with the mounting point. No leaks,just cracked weld where the bracket met the top tank side.
JB Weld, an extra bracket over the top and adjustment of the mount hole (elongating it to line up with where it should be) has solved the strain problem and all is well so far. The rad now sits properly on the bobbin mounts with no side strain.
Have fun fitting yours, and do any adjustments needed! Remember...it is a hand built car!
