The headers are different. In particular, the Long Tube headers are not the same. The firewall setback seems to be about 1 inch further on the sn95 vrs the fox. The fox headers (351w) I went to use curved down 1 inch sooner then needed on the sn95, making the collector hit into the passenger side k-memeberr rear mount. I ended up grind off about 1/2inch of the k-members's rear passenger side mounting flange to clear.
