Browell Aluminum Bellhousing in A-Body - Tunnel Clearance?

[ESDuster]

Just reaching out to see if anyone has experience installing a Browell aluminum bellhousing on a small block in an A-body (Duster in my case). I understand there may be modifications required to the forward portion of the transmission tunnel for clearance and am trying to understand how significant that modification will be. Anyone have experience with this?
Thanks!

I have no direct experience with Browell, but usually the first point of interference is the pinch weld seam that joins the firewall to the floor pan.
If it hits there, the typical fix is to flatten the metal with a big hammer.
