So there's no big online catalogue that I can cross check stuff? Kinda like the steering wheel boss kit catalogues.
Anyhow... i will look into getting some Chaser rails or see if I can use my current rails on the Recaros. Bottom line is that I really don't want to do anything to compromise the saftey of my car/seats and if using the MX83 rails is dodgy then I won't do it.
