Welcome to the site, I moved your thread here to get you an answer to your question. Post a proper intro in the newbie section with some pics when you get a chance.

 

Changing from an 86 - 442 85MPH cluster to an 87 - 442 120MPH cluster should not be an issue from a bolt in stand point.... I do believe the speedometer cables and gears are the same, any GM dealer parts department should be able to verify that for you....

 

Its a direct swap. No changes to your 86' are needed. Hang on to the 87' cluster. They are worth some money due to one year only 120 mph speedo.
