Fiat 124 Spider / Mazda MX-5 ~ Parts Compatibility Guide

Redline Auto Parts has recently published a very comprehensive guide covering the interchangeability of parts among our two roadster variants.  By looking at the photo above from their blog article, it becomes obvious that they actually disassembled one of each vehicle, in order to verify the cross-installation of parts for compatibility, and they they do a nice job of describing any noted issues.

Since they are keeping the document updated (as they wrap-up some verifications), rather than seeking permission to reprint, I’m sharing a link to their great ★ ★ ★ ★ ★  (5-star) article instead: 

They’ve also published a video featuring a side-by-side comparison of the two vehicles:

  1. Very good article. I’m sort of surprised that they didn’t include the tilt/telescopic steering column on the Miata as a direct replacement for the 124. Other than that it’s pretty darn comprehensive.

  2. They probably didn’t tear down 2019 vehicles 😉
    They also mention that the ND doesn’t have heated seats, but they are offered in some versions. This project had to be quite an undertaking, as I sure wouldn’t want to disassemble my vehicle!

  3. I want to add an additive to the gear oil on my Spider. Where can I find the gearbox oil container? I look forward to your help.
