The passengers side latch on my 2000 doesn't lock into place
anymore. I'd like to replace it but they seem to be expensive. Over
$100 for a latch!! Ridiculous.... Anyone know of a cheap place to get
these. I can't see paying more that $20 for one (or an I just crazy).

Nice. Thanks for the link.

Scott, I have no idea how handy you are if you can do this, this is how
I "cured" that problem:  
(1)  I removed the latch.
(2)  I removed the little "C" clip from the pin that has the spring
around it.
(3)  Hold the spring with your finger and slide the pin out of the
housing.
Hint here: If you remove the two latches, you can see how it goes back
together once you have one apart.
(4)  Take the part that rubs on the latch when you use your thumb to
open the latch and drill a very small hole to match a 4-40 screw tap.
(5)   Tap the hole and screw in a 4-40 round head screw.
(6)  Re assemble the latch using the other latch as a guide.
(7)   Install the latches and you will "Never" need to fix it again.

Hope this helps everyone that has this problem.

Total cost, the price of a 4-40 tap and a screw.

Do it to the other one while you are doing it. It is just a matter of
time and they will booth need it.

There are two modes of failure for Miata latches. Some of them are
made so far out of spec that the lock button never touches the latch
lever. These can be fixed by inserting a screw, although the filing
method can fix  these also, unless the gap is huge.

Sometimes the button touches the latch lever, but the mechanism wears
and develops enough slack that the lever will unlatch anyway.
Inserting a screw won't help these, but filing will.

It work fine for the first few years so I think it's just wear. The
driver's side is still fine. I'm getting air whistling in now but I
don't want to adjust the latch tighter until I know it's going to lock
down right. I'll take it apart this weekend. Sounds like a fairly easy
fix.

Check with Planet Miata - they quoted me $55 each for used latches.
But don't take the ones they have set aside for me! <g>
www.planetmiata.com - shoot them an e-mail and they'll get back to you
within 24 hours.

I'm replacing the front latches on the hardtop from my '90 so I can
install it on the '04.  I did remove the side striker plates and the
Frankenbolts from the '90 before she went away so that saves me a
bunch of MSUs.

Do the latches from an NA work with the NB ?

I know the latches were changed midway through 2003 so prior to that,
there's not a problem, other than adding frankenbolts and striker
plates for the side latches.  See http://www.miata.net/garage/hardtop/ 
for full info.  According to that, if you have the old style striker
plates and frankenbolts, all you need to add is new front latches.
Since my 1990 hardtop does not have a defroster, I don't need to add a
new pigtail for that.

Hmmm, wonder if Planet Miata will give me a better price if I trade in
the old latches toward the new ones?

It looks like you can get from $50.00 to $70.00 for them from through Ebay.
This latch set looks very nice for less than a single latch from the
stealership.

I meant the softtop latches. I don't have a HT. :)

Ah, sorry, I misunderstood.  I know that the compatability guide at
miata.net says you have to replace the whole frame for an NA softop to
fit an NB so I would assume the latches have to be changed.

Why would anyone out a NA top on a NB?
I also thought that the two frames were interchangeable between the NA
and the NB.

Leon, don't you have a factory NB top and frame on your '96 Miata?

Yes.  The frames are not the same, since the NB is designed to lower
the glass window.  But IIRC, the latches are the same.

Yes, the NB frame uses a different system to pull up the window, as well
as springs that lower the top without needing to push the window down
like the NA frame/NB top conversion that I did.

Still, both tops have the same dimensions. The NB top fit on my NA frame
just like it would have with the NB frame; same hole sizes, same cable
lengths, same rain rail holes, etc.
The earlier frame just needed modification to pull up the glass window.

Since the NB top and frame can be put on a NA Miata without
modifications, I was guessing that everything besides the top attachment
system and the springs on the frame are the same.

FWIW, I was concerned about this with my 2001. I bought it used last April,
and both latches were defective. After I tore them apart, I realized they
never did work correctly because they were machined incorrectly and couldn't
lock. I put them back together and decided to live with it for a while to
see what happened. Neither latch has ever opened or even loosened while I
have owned it, and I suspect the same was true for the previous owner, or he
would have changed them under warranty. There probably isn't much of a risk
of the top blowing open, or I would think Mazda would have a safety recall
on them.

Yes Dana,  I had one of those latches on my 2003 and that is the one I
started on when I drilled and put in the screw. It worked so good, I did
the other one. Very positive lock with them now.
