The delco is a little smaller than the original Marchal but fits quite
easily in. I had the help of a good alternator guy, but basically once
you sort out which wires go where its just a matter of mounting it on
the old bracket. We had to do some fitting to find a belt and pulley
setup that will work.
There are many benefits to this upgrade:
1/ You can get a replacement alt off the shelf at any Delco dealer.
2/ A new one costs less than a rebuilt Marchal or Bosch
3/ More power. As I say if your into serious electronics, stereo etc you
can easily swap it out for a more powerful one.
4/ You can buy a chromed one if you want right from JC Whtiney. (Idont
know? Some people like them;)
5/It uses bigger better bearings than the original and should last
longer.
6/ Any alt shop can rebuild it in an hour.
BTW I did this five years ago and have not had a problem. I get good
voltage and the battery is always at full charge. I noticed that the
starter runs faster than it ever did. Even with all of the accessories
lit up the red warning light doesn't glow.
If you know someone with a shop that you trust it might make it simpler.
We had to try a few different belts/pulleys to make it work and they
have all of that stuff on hand. A small mounting bolt sheath was
fabricated to brace the bolt mount to the original bracket. Its all
pretty straight forward once you get under and have a look. 
Good Luck
