Unfortunately, there is a better chance Slappy that your car is a clone than Saleen back in 89 not installing a strut tower brace. Saleen was at their peak production in 1989 and not skimping on parts. 1989 is most knocked off year for foxes simply because of the number of engine bay plaques and console shifter plaques. I have seen a few 90 and up fox body cars without a strut tower brace because of the factory blower.
Slappy, you just purchased your car correct? Can you trace all of the owners before you and the dealership that it was originally purchased at? Also, has your car been out of state? You are in Washington state, correct? Are the factory rivets on your vin tag on your dash silver or grey? Take as many pictures as you can of your engine bay (placement of your engine bay plaque so I can measure) take pics of your driver side door jamb where it latches and the door. If you don't want to post the pic's pm me.
I have seen a few really good clones. Also Slappy your car is 89-0175 correct? If you would like I can ask someone internally at Saleen where your car was stamped.
