In that case it's well worth it.
I believe only the GL lacked the remote fuel flap release - which is a pretty fundamental flaw really. Get a S/Fairmont/Ghia fuel flap of the same colour or install the closing mechanism (on the flap itself) from one of those models, and after installing the motor, the rest should be very easy.
