I have since sold my 78' Corona wagon, because I came across this 72' Mark II wagon.  It currently has it's original 18RC motor, but I recently purcased an 18RG DOHC motor that I am going to freshen up wiith a new/complete gasket set and dual Mikuni 44 carbs.  I also have a low miles W58 transmission out of a Toyota Supra that I am going to swap in.
