This top letter and the original from Sports Car Forum began the discussion to support Don and the Sports Car Forum Alpine.
On the left is the brochure from Baugh driveline. They produced LSD’s for the Alpine and I would guess Tigers’ too.
On the right is the Rootes advertisement for the American Racing Silverstones. Believe it or not, they sold these with different offsets on the front and rear wheels….. I had wondered why the sets I have were like that. Well, it was the way they could have the front and rear track widths closer to each other.
