MG MGA - Carburetor Damper Piston

I am about to reinstall my carburetors after pulling them for a clean up and to replace a leaking float. I noticed the confidential service memo on Barney's web site regarding a change to a shorter piston in July, 1959.

My carbs have the longer, original style piston. Anyone have experience or thoughts on going to the trouble of shortening my damper pistons?

That Confidential Service Memorandum refers to the mga twin cam.
Normally when a CSM refers to several, or all models, they are listed.
Do you have a Twin Cam or can it be confirmed that it applies to all SU's?

You are indeed correct. Thanks for the clarification.
