[Miata] Fw: Replacing rear window

Wed Jul 2 19:48:02 CDT 2008

Got you,  overdrive would be a better word.  At 60 mph I am at exactly
3000rpm,  seems high.  2200rpm would be better,  does cold intake and
improved exhaust or turbo help to improve?

Skip the 6 speed there is no extra economy to be had.  Look at the ratios and
you will understand.  1st gear is a stump puller and 6th is almost the same
as 5th on a 5 speed.

Thanks, new to miatas.  Quite a cult group.  Two months ago bought the red 97
with 49k miles on it and a good car fax report.  Wanted fun way to get better
mpg.  Top had been down for four years.  Boy did it crack when raised.  It
has 17 inch flashy wheels.  I am a pretty handy engineer.  My eight year old
wants it in eight years.  Want to do some after market things with it.  I
wish I had a six speed for better economy.  I am on BB or I would send a
picture to you.  Did get ticket for no lisence plate in front.  There are no
brackets and it would look awful.  Now I have to do the timing belt but I
would like to peek at it first to see condition.  Possible?

Hi, Mark!

I think the grinding wheel on the Dremel will disturb the plastic less than a
drill would.  You can still carefully move it away enough to tape the holes
without removing it.  I think I didn't bother to tape the holes on the last
one I did.  I like your idea of zip ties on those side rivets.  I'll do that
next time.

        Hi sam, unfortunately, while drillimg rivets, that's when I cracked
it plus I wanted to seal both sides of the rivets holes.  It was my first
time doing  this on a miata.  Done mg and triumphs and two fiat spiders.

        Thanks

        I've had luck grinding the heads off of the rivets at the back with a
Dremel.  Then push them out the back one at a time and you can separate the
top from the rain rail without removing the rain rail from the car.  Much
less chance of cracking it this way.

                Hey Alex, funny you ask.  I just did mine on my 1997.  Miata
garage has a good article to follow although the beginning is a little
confusing so I ignored that part.  Just take out the rear carpet by removing
the plastic fasteners.  Then you will expose several bolts holding on some
plates to some studs.   They are 10 mm.  You will see several rivets to drill
out.  Use a very sharp drill bit or in my case bits and variable speed drill.
This is a real pain if they start to spin on you.  Hold with needle nose vice
grip.  Once out you can separate the top from the rain rail.  The rain rail
like every one says is real fragile.  I broke mine in a couple of spots.  If
you do the same, just go to the hardware store and pick up drain plumbing
tape and tape her up real good.  It is thick gooey tape with a paper backing.
Sticks to anything.  Just tape the whole thing up nice and pretty.  You wont
be putting rivets back in so tape over the holes.  Rivets are just for
factory convenience.

                Now there are two more rivets or I would call them brads that
hold the rear curtain containing window to the top.  Drill them out too.
They are a pain along with two rivets holding the top on each side of the car
near the bottom of seat belt tower.  They are a pain too.  Two on each side.
Now the zipper holding window in has these little metal stops at the end of
the zipper.  Bend the prongs out and use needle nose to remove.  Mark both
sides of zipper with red nail polish.  You want to put the stop back in the
same place.  Now run the zipper off the track.  I took the window to a very
nice mom and pop upholstery shop. They put a new window on the inside of the
curtain and double stitched it on.  They also stitched Velcro on that was
coming loose.  Real pretty job for $70,00.   Put it back together in reverse,
don't scratch your new window.  Now those two rivets that hold the top and
curtain together can be replaced by using slammers which are two part rivets
that are pushed together.  They really hold very well.  I ordered from
Mcmaster Car.  The two rivets on both sides are real hard to replace, so I
used small electrical zip ties to secure top in those locations.  Make sure
your rain rail is taped up real well and the drain tube on each corner should
be cleaned out while you are there.

                By the way if you screw up the zipper stop like I did, ask
the upholstery shop for one when you pick up your rear curtain.  After I did
mine, I noticed just a little flapping noise between the top and the curtain
by the sides of the window.  There is suppose to be a little rubber pad
there, mine is a little worn.  I wanted to add another piece of Velcro but
have found no glue to attach to top and curtain.  Self adhesives one wont
stick either.  Took me four hours to take apart and three to put back
together and roughly a six pack or so of beer, this might be a conservative
estimate though.   If you have an original top it has like a little embossed
or raised area with writing on the corner of window in Japanese.  That is the
real deal..I would be surprised a 1992 would still have original.  If it was
after market you could get a new curtain with window ready to go if the
zippers would match.  Miata has proprietary zipper so if yours is Miata, no
one makes one to match But if top is OK and curtain is OK, I would go with
the upholstery route.  There also is Velcro that hold top to cross bar near
back window, you can tighten the top up some by moving Velcro towards the
window.  Its wrapped right around cross bar.   Hope this helps some.
