I looked at the EPC quickly, because I know how irritating this could be...
As for the Hard top components, there are part number changes for handles at the B-pillar mount as well as the window frame fastemers, but without indication as of which chassis, which usually means that these changes should not create any fitting issues.
There was a change indeed in chrome B-pillar top moulding as of chassis 042 015567, with the new chrome also installed on 15546, 15551, 15555, 15556, 15558, 15561, 15563 and 15565.
But I have no idea if it can be the cause of rattling as I do not know the nature of the change. What i would expect is that if the change was important for holding the top, the top elements would also change "as of...". But I cannot be sure about that.
SLS have these moulds "as of March 66". Probably the same change. They do not show different handles.
When I had issues with rattling of the soft top, I asked my daughter, while I was driving, to hold/press on various parts of the top to see what was rattling. We found the reason this way. If you have someone, e.g. press on glass while driving, you will figure out if it is this part.
