I do not think the mast bases changed.
By "pin", if you mean the hinge pin, it is not working when the mast
is rigged and when sailing--it only takes the load of raising and
lowering the mast.
There is a locating pin in the base of the mast that does the work to
keep the mast base in place when sailing. Theoretically you could
take the hinge pin out while sailing.
If you have any concerns about your mast base (or mast), call Buzz at
Ballenger. He has or can make all the parts for our rigs. I just had
him make me a new headstay and backstay.
Which is a good reminder for everyone: inspect your headstay (top &
bottom) regularly--the original rigs have no toggle at the top of the
headstay, and flogging jibs and floppy headstays lead to failures at
the top swage where you can't easily see them. My last headstay was
broken nearly halfway through when I got lucky and noticed.
Buzz mentions that most backstay failures in our types of boats are
below deck, so be sure to inspect your entire backstay tackle
carefully. If the tackle fails, you can lose your rig.
