No, it's not easy, but there are quite a few who have done it, so I'll give you a bump to the head of the line.

Do a thread search on Central Coaster. His conversion came out real nice. Maybe you can benefit from the mistakes he made..

CC did the most comprehensive write up(s) on the swap, so definitely check that out. He also has a VERY detailed chart listing parts by model year, clutch components, bell housing measurements, etc.

I did the swap too, and it was no picnic. There are a few pitfalls. First thing to decide is what you plan on using for a flywheel (dual mass, your single mass, aluminum, etc) and hydraulic / clutch set up. Then go from there.

I tried the search feature and had no luck either. The search feature is not at all user friendly.
