With regards to the Monterosso Mk1 Escort, I will quote from Lee Nicholle on a different forum (if i am allowed),

The Monterosso Escort went to Ron Newbound who fitted a rotary. He crashed it big time at Winton and rebuilt the car with a new shell. he used parts of the roll cage and rebuilt the front space frame the same as original. It looked and performed the same after. Probably a better car as the original neded a LOT of work when Mick aquired it. last I knew Kevin Eyles from Victoria had it, still with rotary power.
