TABC Diff Flange

[cameron@magma.ca]

Roger My TC differential drive flange measures as follows: Diameter of boss 1.807", which I would guess is 1 13/16" with a generous tolerance and would vary from car to car considerably. Outside diameter of flange ("external width of flange across the diagonal"?) 3 3/8" nominal. Bolt holes centres are on a pitch circle diameter of 2 3/4", but are not equally spaced. That is, they do not form a square, but a rectangle 2.105" by 1.769".Take these dimensions with a grain of salt, say plus or minus .005" David Cameron
