After my crash repairs the engineer added a support frame for the radiator in place of bolt in fittings as provided by the original chassis manufacturer.
Installation matches others earlier descriptions in that the radiator is pinned and these mate into rubber donuted holes top and bottom in the radiator frame.
Lower part of the frame is bolted into place once the radiator is inserted into the upper frame portion.
Obviously to suit your application some though would be needed to make up an equivalent frame but am sure it is all do-able.
Pictures may be a little small but I can't access my photobucket account at present so these will have to do.
Could send large photos via email if you wish just PM me if needed.
Cheers
