I had an issue develop on the GT6 last week, I was getting a vibration coming from the nearside rear of the car on braking.
I suspected it maybe a brake drum that had worn oval. On investigation I jacked up that corning of the car and partially applied the handbrake. On rotating the wheel I found that the brake was dragging for part of a revolution and free for part, confirming an issue with the drum.
I ordered a couple of new drums and as luck would have it already had a set of New Old Stock Lockheed Shoes in my parts stash.

I spent yesterday evening changing out the drums and shoes, after a quick test drive I confirmed that the vibration has gone away. Good news and a fairly quick fix although not cheap, a pair of drums was over £80 with carriage, last time I bought a par it was about 20 quid, however, thinking about it that was over 25 years ago!
