It just depends on the width of the seat at both the shoulder line and at the hips. Given that the SRD is a reclining seat, I would tend to think that it won't fit due to the extra width at the rear, and the way the tunnel is constructed, you'll need to cant the seat out of position.
Best bet for most has been a Kirkey seat. Due mainly to the dimensions of most of the OEM/Aftermarket stock type seats out there measuring between 19 3/4" up, width wise they make for a tough fit in the Coupe.
To be able to position a seat correctly, the max I've found usable has been 18", and that was really pushing it.
