A copy of the regulations is available below:
The only significant change this year was the inclusion of FIA Group 1.
Some interesting excerpts from the Supplementary Regulations:
Entry fee and prizemoney
The entry fee was $48.
Again, the absence of a major sponsor meant a relatively small cash prize pool of $2,000. Additional non-cash prizes were given but were not detailed in the supplemntary regulations.
Vehicle eligibility
Vehicles had to be roadworthy and two-wheel drive and like the previous year, eligibility was aligned with FIA regulations with the addition of Group 1 (Series Production Touring Cars with 5000 annual production units). Group 2 was now Production Touring Cars with 1000 annual production units and was characterized as a mixture of the old 60s Group 2 and Group 5 rules (the old Group 5 ended at the end of 1969). The new Group 2 could be quite freely modified compared to the previous Group 2 regulations. A new Group 5 (25 units manufactured in a year) was introduced to test prototypes. All vehicles were permitted modifications in such aspects as extra lights (maximum 6), internal crew protection, under body protection, additional fuel tanks etc.
All vehicles had to carry a first-aid kit, fire extinguisher and reflective triangles. Seat belts, proper mudflaps and towing points were required. Roll bars were still not compulsory except for open cars.

Timing and Scoring
Timing was to the forward minute except on Special Sections with crews able to nominate their time if early. Scoring was strictly 1 point per minute early or late, with no provision for Special Sections, which were presumably only timed for the purposes of special awards.
Wrong directions or missing a passage control cost 25 points, no different on Special Sections. Missing a main control (or exceeding late time) cost 200 points.
Exceeding late time at a stage end resulted in exclusion. Late time was prescribed to be 180 minutes per stage. The event was broken in four stages each with two divisions. There was no requirement to complete any particular proportion of the course in order to be classified as a finisher.
Other
Starting order was by ballot within five categories which unlike previous years, reflected the more international status of the event. The first category was drivers who have placed up to 6th in an international rally. The second category was for drivers placed up to 12th in any international rally or up to 6th in a national championship rally. The third category was for drivers who had placed up to 3rd in class in an international rally or up to 12th in a national championship rally. The fourth category was drivers who had completed the course of an international rally or national championship rally.
Cars were permitted to be worked on at any time, including in control, except for the impound at restbreaks.
