1987 3.8 SFI Turbo Regal Engine Description Manual and 1984-1987 Buick Regal G-Body Sunroof and T Top Trouble Shooting Booklet
This information has been gathered from my personal collection of original Buick literature. This handy booklet is 8 1/2 by 5 1/2 and is 87 pages. The first section has illustrations of the various parts of the 1987 Turbo Regal engine (be the same as the 1986) and in many cases provides the GM part number in the illustration.
The second part of this handy size book is a trouble shooting guide for the factory sunroof and also the factory T-Tops. It goes into great detail the issue and the solution for the various issues. At the end of this section for both the sunroof option and the T-Top option we give each GM part number for the various parts including the illustration showing the actual parts.
Now you can have all this critical information in one handy spiral bound booklet.
