Installing aftermaket seats

[Lui]

Just got some aftermarket seats that I want to install in my car. They don't come with rails.
Does anyone know any places in Perth that can Install Aftermarket seats to my car?
Where can I buy some rails to fit my seats?
Is there any places that can adapt the stock rails to my aftermaket seats?

"Is there any places that can adapt the stock rails to my aftermaket seats?"

i put a bride brix on a stock laser/323 rail.
was very easy cause the stock seat just unbolted from the rail.
i then bolted plates to the stock rails & made mounting holes for the new seat in the plates.
make sure you use high tensile grade nuts/bolts
