Join me on Facebook! http://www.facebook.com/TomsturboGarage In this episode we give my 1987 Buick Grand National some much needed attention, specifically to the differential and rear suspension. This is the second part of a multi-part series where we're making a host of modifications to this American classic to improve its performance on the street and strip.
