Well, for starters, always remember one very important definition:
WIFE: the voice of reason that prevents a K5'er from obtaining certain "needs"
I would suggest getting the 'security' and 'safety' taken care of first. This means make a listing of all relevant components for insurance reasons, and talk to your insurance carrier regarding what they will cover. If you read the posts earlier regarding this topic, you'll get the idea. Also, check safety items like seatbelts and brakes, for obvious reasons. Then, you can get into the engine and suspension.
What not to do: Don't proceed on any project without posting your idea first ! This website can and will save you many headaches when you start thinking "big". Take advantage of the information shared, and you'll do fine !
Also, do you subscribe to any 4-wheel magazines ? That's always helpful for "do's" and "don'ts"
Good luck, have fun !
