Cowl induction

Hey, looking for a good cowl kit for my 91' tbird. But I cant seem to find the correct size. If anyone know where I can find Hoods or a cowl kit let me know thx.
(also anyone know why my 91' bird is a sport... I've looked into it but it looks like they started production for the sport in 92'. any info?)

unless someone put a badge on it that says sport.

no one makes a cowl induction kit, but there are a few companies that make cowl hoods. age classic, motion, and cervinis all make hoods for the thunderbird.

Springs are the same as a supercoupe. A little higher spring rate than non sport/sc. There more be more differences but that is what I can think of at the moment.
