From what I understand the replacement is next to impossible without major modification. But you may try to find the engine at a junk yard if you just need something to work. I wouldn't waste my money with a rebuild of a 420a but it would also depend why you need a "rebuild". If your timing belt snapped it would be better to get a junk yard engine and do a gasket rebuild on it.
