I was the one who fabricated the strap for the older metal lever seats as well. On those trucks (95-01) the metal gets bent from getting in and out and then eventually snaps. The fix for that is also a fabric strap… we have a thread going for those seats already
This thread is for the 01-02 trac seats are the worst!
The whole handle is plastic and they pull on cables to do the recline on each side. Once the plastic handle breaks ( like in the pic) you are left with just a little knub.
This is why I glued (e3000 hobby glue) and ran a large aluminum Rivet through the broken plastic bit and added a bent piece of metal. Notice the metal is placed underneath the plastic knub, this way leverage pulling up is in your favor
The metal gives the length needed to gain the leverage for pulling the cables. I added a strap so your hand has something to grab onto and the handle no longer sticks out where your hip is going to hit it when getting in and out
