I'm pretty sure that the disc you have is for a later BJ8. they used a
thicker disc 1/2" I believe and a different offset. They were the same
diameter. If you look closely I think that you will find that the disc is
not centered in the caliper.
Before getting into the driveshaft issue I would check the tightness of the
rear wheels on their splines.
Jack up one rear wheel and, with the hand brake firmly applied, try turning
the wheel back and forth you will probably find that there is play. If
tightening the knock off does not resolve the problem then the mounting
taper inboard of the spline is probably worn and the knock off nut is
bottoming on its thread.
Usually in such a situation new splines and wheels are required...:-(

Fellow Healeyoids,
Brakes: The disc box looks very old (60s-80s) and says Austin Healey 3000
(wire wheels) 1960-68. The disc is a Lockheed replacement disc part number
BG16. Other numbers are International Parts Service SS 73966 and Foreign
Car Parts #92804. The disc has the same diameter. The disc is about 3/16
thicker but my old ones have been turned down. The new disc is also thicker
at the flange and it was very difficult to get the five bolts to the hub
tight. The flange is slightly steeper sloping from the flange to the disc.
But, as I understand it, the BJ8 discs are different. Maybe this is the BJ8
disc?
Clunking: I'm going to check the driveshaft out again. I think that the
clunking appeared when the car took up the drive and when I let off. This
makes sense that it is the rear end or the driveshaft. I'm leaning more
toward the driveshaft now. Also, I will double check all of the shock
mounts and tighten the wire wheels again.
Carpet: Fellow Healeyoids are working on the orientation as I write this.
