Default M42 Compatibility

So my m42 took a shit and I'm looking to swap in another. Of course, when I don't need one there's a million for sale from swaps but that's life. I'm wondering if an m42 from a '94 3.18 will slide right in or are there major differences? Any input is well appreciated. I'll probably just get an m50 but I like the light engine up front. Thank you all for your time.
