#904 Requires 1 3/4 inches of clearance between the rocker rail and the exhaust pipe on the passenger side. The driver side is not an issue.Global West Advantage:
The subframe (frame stiffener) is bent to follow the floor contour and install up next to the outer rocker rail. The unit welds into place at the firewall and rearward at the bulkhead next to the rear lower arm mount.
The subframe spans the full length of the passenger compartment. The 904 subframe tucks up tight along the inside of the outer rocker rail. This subframe cannot be seen once it is installed. The 904 also acts as a jacking rail so you can easily jack the car up for service.
If you are installing a roll cage, the 904 is in the correct location for triangulating the cage directly to the subframe.Note:
In some cases, the exhaust on the passenger side may need to be shortened or adjusted. To see if this is necessary, measure the distance from the rocker rail over to the exhaust.
If the distance is more than 1 3/4 inches, the subframe connector will clear. If the exhaust is closer, you will have to shorten the straight portion of the exhaust pipe behind the front tire before the bend by one inch. None of the exhaust hangers will need adjusting.
