Hey guys, I have been offering these to the rotary FD community on the other RX7 forum for a while with many satisfied customers and just thought I would post here too since the same issues with crumbling plastic door lock cover plates ("dust shutters") does not discriminate based on whether there is a rotary or piston engine in the FD...
The kits includes a black finisher plates, new clean, white, plastic OEM type shutter pieces, and new springs. This will give you all the parts needed to rebuild the door lock outer dust shutters in an FD door locks. In case you are wondering, the dust shutter is the part that flips in as you insert the key in the door lock. The FD dust shutter is white plastic on both doors, presumably because Mazda included a door lock illumination lamp in the driver side door lock and the white shutter will illuminate when the lamp is on.
Because the shutter itself is plastic, it degrades over time from exposure to the sun, etc. eventually turning yellow/brown and finally crumbling into bits and falling into the door lock mechanism. When this happens, you can pick out the bits but then your door lock will be open to the elements and you then have to deal with the missing shutter. Mazda never sold the dust shutters by themselves however up until a couple of years ago new lock assemblies were available, they were $$ but at least there was that option if the shutter had failed. New locks are NLA now. This kit rectifies that problem. You can rebuild your door locks with a nice white OEM plastic shutter plate, a new spring (if you have lost the original) and a fresh black fascia plate to replace the scratched up original. If your car still has original dust shutters, they are probably pretty beat up by now if they even are still there at all.
FD's came with two styles of door lock finisher plate, chrome and black. My car originally had chrome, most seem to have used black. Unfortunately, the chrome shutter kits are NLA now, only the black style is available. However, if you have a chrome finisher plate and need a new shutter this kit will still work as the shutter and spring are exactly the same, and the finisher plate is also identical except for black versus chrome. The original chrome finisher, even if scratched or rusted, can usually be restored with chrome polish - so it is still possible to rebuild chrome style lock using the original finisher plate. Or, an originally chrome plate-equipped FD can be fitted with black fascia plates - the parts are the same except for finish.
A pair of kits is $24, one kit per door lock (i.e. two kits per car). Shipping via USPS with tracking is $6 per order conus. International postage cost varies, usually $15-18 for a First Class mail package. Shipping is weight-based, so about 10 kits can be shipped for the same cost. More than that, a different package is needed and cost goes up slightly.
Here are some images of the parts included in the kit, and a nice Montego Blue FD with kit installed installed...
Please pm me if interested. Thanks!
