I have the following expired belts for sale. All are in good to excellent shape. These would work well in a cobra for street use. You could also send off the crow and ultra sheild and have them re-certified for fairly cheap.
1 - Crow Enterprises Cam Lock 5 Point harness. Black in color. $40.00
1- Ultra Sheild Cam Lock 6 Point harness. Black in color. $40.00
2 - Deist Latch and link lap belts. Bolt In. Black in color. I also have the y harness for driver side. These are 90's vintage from when I first built my cobra. $40.00
