Recaro seat rails universal?

[NicPM35]

Just got some Recaro seat rails on the cheap for my car (stagea).

My question is: do all recaros seats use the same size rail? (and other brands respectively as well) 

ie. if I have recaro rails can I safely go out and whack any recaro seat on it? 

I'm looking at nabbing seats from an Evo X, unless anyone else has any good leads!

I put some Recaros from a Honda into my S1 Stagea and had to use something like this (plus some adapters IIRC):

I suspect you will have to source some special rails to fit EVO seats. Try to go to a wrecker and have a look at some to see what you are up  against.
