Can I replace M9R 782 with M9R 740 engine

Hi

I have a Renault trafic, my timing chain snapped and I have been advised I need to change the engine

Have been looking for a replacement complete engine as the injectors are seized in the the engine



These things are like gold dust!



I have found an engine, it is M9R 740



The guy selling it says it will fit but I need to be sure



Can anyone advise please as I don't want to spend money on something that won't work
