Length of [fixed] tie rod?

[Frix]

Does anyone know the total length/outer dimension of the fixed tie rod for the rack & pinion steering on the -75 Super? They seem impossible to find these days, just the adjustable ones are available. I have two adjustable rods fitted, but that just adds up too many possibilities for the tire shop to set the correct values... My plan was to lock one of the rods to the same length as the fixed, and only let them work on the other side. Just like the original setup...
