Hi guys,

After discovering that my lower shift boot was torn again I found out that
there are 2 types of lower shift boots: M514-17-480A for '90-'93 with a
large metal ring and M513-17-480A for '93-'05 with a small base and higher
rubber part (see
http://www.xs4all.nl/~jfeelder/miata/techniekaandrschakelrubber.jpg ). Both
parts fit my '91 Miata and I think the M513 has the advantage. This one
won't rip as fast because of the added amount of 'moving rubber' parts.
Furthermore, it seems Mazda had already developed the M513 part when the
M514 was used. My questions:
- What's the use of the large metal plate on the M514-version?
- Why should I use the M514 if the M513 fits just fine?
- Why has the later model a lower partsnumber?

Sent before finished, sorry.


I think the answer is that Mazda has NOT superceded the earlier part #
with the later one so they must intend for you to continue to use the
M14.  It costs them money to maintain 2 different part numbers and if
one could replace the other you know they'd do it, right?

found this for what it is worth...

says the newer part will fit on the older box but the older will not fit
on the newer...  looks to me like they just simplified the design to cut
costs.  i doubt that there is any significant difference in life span of
these two parts and the purist in me says to just replace it with the
same... after all since your '91 boot lasted until 2010.

That is about the maximum amount of time that I have seen one last. They
wear out so fast that I am barely able to care about replacing them.

It seems like a different material, or at least thicker rubber piece
could be used, but that would mean less rubber boot sales for Mazda.
