GTV 1750 mk 1 seat rails

[Alfa1750gtv1]

Hi All,
I've been searching in vain for some correct seat rails for my 1969 GTV 1750 s1.
Because this is pretty much an impossible exercise to find some at all in even remotely usable condition I was going to re manufacture some.
This all seems relatively straightforward (if too expensive for what it is).
However I'm stuck on some measurements as I have nothing to actually compare it to except about 3 photos on a google search.
I have attached a file showing the measurements I would like to get that would give me the best chance of maintaining historical accuracy to the originals. And a pair of the type of rails im alluding to.
I would love if someone could help me by measuring their own set so I can compare to that.
I'm happy to pay if that's what it takes but I would also like to make these available to the rest of the alfa world as so far as I can see there's nothing out there currently.
Cheers, James

Did you end up getting the measurements you wanted?
My 69 Mk1 GTV has it's seats out and rails off at present so I can measure or depending where you are located you could come and measure up. I am in Glen Iris Vic.
