Like most convertible tops, the Miata uses steel tension cables that are threaded into the pockets that run along the side windows.
You can check your existing cables easily. With the top up and windows open, run your fingers along the edge of the top until you feel the cable inside edge of the top. If it feels tight, then it can most likely be reused when you replace your old convertible top. If it is loose, then it still may just need to be retensioned during the installation of the new top or you may need a new set of spring loaded tension cables.
An installer can also repair damaged tension cables, but if you would like to also replace the tension cables at the same time you replace your convertible top, this is the item you need.
Replacement cables for convertible top did the job, no complaints.
Good Quality !!!
The tension cables that came with my 1992 rails were broken. There is a plasticy square shape that attaches the cable (wire) to the rails. It is riveted into place. Both of my plasticy parts were cracked and broken. These worked well as replacements. I had to remove the old rivets and rivet these into the rails. I had to remove the spring included with these cables to feed it through the top and then reattach it one through the soft top for ease of installation. I then was able to bolt the spring to the rails. The hole that the washer / bolt combination passes through in the spring was a little small but it was easy enough to stretch into place. Overall, this fixed the problem. They look like they will last and are all metal (no plasticy parts). The crimping to the cable seemed professionally done etc. I am sure they will last for years and years.
These cables are a little bit stronger and thicker than the OEM ones I took off. These cables work great!
I thought I might not need these but the old ones had a frayed jagged jacket. These worked well.
