Have you tried the usual suspects: r.d. enterprises, Dave Bean, JAE...?

Why not fit the correct ones?  0.625" Cylinders will reduce the amount of force on the brake shoes. Ray at RDent.com has them.

It appears BP Northwest has them.  I think that is where I bought mine.

That was the same issue as with the Moss catalog. It says GT6 MkIII, but the item pictured does not accommodate the self adjusting assembly on the TCS and later GT6 MkIII.

But it sounds like the other vendors mentioned know the difference. I just chose PartsGeek because I've had good luck with them in the past and shipping is really reasonable.

The rear brakes on a tcs are "self adjusting" via the handbrake.  The late  GT6 mk3 rear brakes are standard "stock" on a tcs.

The new brake drums I installed last year were balanced.  The original brake drums were not balanced.

Where did you get the drums from?  I just about fainted when I heard one of the usual suspects quote $350+ for ONE new one.

At that price, it would be time to convert to discs unless you were really serious about originality.

"the original drums were not balanced"  Amend that to "the drums that were on the car were not balanced".

Lotus used balanced drums very shortly into S1 production.

Inexpensive 1.5" drums can be found here:

Probably elsewhere as well.  THEY ARE NOT BALANCED and need to be balanced first.

The rear brake cylinder from BPNW shown above is NOT for the self-adjusting system used on the TCS.
