I used the TSM's on my Cobra. Seville Calipers, but when I bought it nothing else was available. Calipers bolt up nicely to the brackets. I added one inch to the emergency brake bracket and the II cables fit perfectly. The bleeder screws don't end up verticle, so I've either gravity bled them or used a pressurized bleeding system from the master cylinder, doing this requires them to be laying on the leaf springs with the bleeder screw upright. No brake pedal bleeding.
Currie offers an 8 inch kit using the later model red Cobra calipers.
