I have a 2003 Mustang Cobra with IRS and I am going to a live axle. I heard that some people are putting the IRS from the Cobra's in the RX7's for Autocross and things like that. I am asking $900.00 OBO. I am in Ocala, FL but get my car worked on in the Tampa/Clearwater area, which is where the IRS is. You can contact me at UFJenn21@aol.com or call Sam at Coastal Chassis Dyno at 813-849-2423. We can work something out with shipping. Just let me know. Thanks.
