Hotrod,

In this picture you see a black sharpie line, the reason for this is to simple mark alignment, the guys at GMC back in the day were geniuses, the 6 bolt hold you see for the crank to flywheel are at a perfect match, you CANNOT mess these they only line up one way correct to put in the bolts, one hole is offset slightly, so you cannot misalign. IF you decide to put in a 700R4, you need to purchase a flexible dip stick NONE of the stiff sticks styles will fit because of the angle of the inner fender and exhaust headers.
