I had to notch my Lakewood's flange on the passenger side with the 2" RB, TTI's. All the bolts that clamp it to the block saver plate are unaffected, as it didn't go beyond that radius.

This combo goes in my '70 E-Body, but the fitment on the engine trans should be the same. I can take some pictures if you want to see where I trimmed exactly.

Not an issue unless you need to get the car inspected during tech, and then they may not notice it. Any modifications to the scatter shield do affect the SFI rating unless signed off by lord knows who.
