Miata and RX7 part interchangeability
 

Does anyone know which parts can be interchanged between the Miata and FD, if any? Like for example, would handbrake grip for the Miata fit on an FD? I was looking at some Team Voodoo shift knobs and brake grips and swear I read on the forums over the years about some part interchangeability but couldn't find any threads. It'd be nice to have a reference list of parts.

Many of the cowl and other plastic fasteners are interchangeable.
I have a weighted exotic wood Miata gear shift knob in my FD.

Here's what I *know*.

Steering Wheel (needs to be redrilled)
Radio (Needs new harness)
Shift Knob
eBrake button (don't know about eBrake itself)

There's gotta be more - I just don't know what they are.

If memory serves well, seat bolts (that go to the floor) are the same :)

Thanks guys, keep it coming if you remember anything from over the years in the forum and etc.

Not certain about the Miata other than the E-brake release buttons definitely work.
3rd Gen. Ford Probes also share obscure bits... cowl screw covers, hood prop rod retainer clips, the anchors and ropes for hatch covers, all the interior plastic retainer clips, etc. They're also a cheap source for some of the electrical connectors off the harnesses.

Those rubber plugs that cover the wiper arm nuts!
