I just used 1200 rails with a couple of tabs welded to narrow the bolt hole arrangement.

They're a good seat.

If you get a set I can send you over the dimensions or even copy my set of rails onto your.

I'm planning on redoing mine when I get some spare rails so I can put the lever to on the inside (between the legs and under the seat) at the moment the levers are on the outside and had to be bent a little to get them to fit in the space between rail and outer sill of the car.





EDIT: Sorry in the previous post I said I had extended the bolt holes outward, I meant the opposite!
