No way for us to know if you're over your head as we don't know your mechanical ability. Do you have a bellhousing? The three speed and four speed do not share the same bellhousing bolt pattern where they bolt to the bellhousing. Some bellhousings do have both patterns, though. One end of the Z bar attaches to a bracket on the bellhousing and the other to a bracket on the frame rail. Needless to say, you'll need those brakets as well.
