200R4 update

Quick question, the cut/folded pinch at the front of the tunnel:

Was that because the dual bolt pattern bellhousing is too large or because of the filler tube?

I was looking at that and its making me think of going the 700r4 route if the duall pattern bellhousing is an issue(yes i know worse gearing), but the auto tranny for my car temporary anyways. Gonna go stick down the road after i Axe the T-bars.
