Hi guys. Have a problem with my aftermarket pans seat rails. They don't look like one of the ones from my original pans and when trial fitting the seat it wouldn't fit.
So basically trying to work out what are the original seat rails as my old pans had two different types as well.
This is my original drivers side seat rail. Unfortunately I only have half as I had to cut one rail getting the pans out.

This is th original passenger side.

This is the reproduction one.

And this is why it's not working. The seat is hitting the teeth. I tried manipulating it but no go.

So which one is the correct rail for for my 69?
Thanks
