        3 2001 Cobra - CrazyCarl17

        Great product wrong application

        I have a WAP Cobra block from a 2001 Cobra. The bolts do not fit my block as they say that they should. I had to get the later style from a 2006 mustang GT.

        Great products

        ARP is the name in high performance hardware, well worth the extra money spent if you want your high HP Build to hold itself together!
