which tranny shield should i use

I have a 69 dart with a 727. I am running the CSR shield. It did not fit to bad. The only problem is the rear of the shield. It has a lip to keep the pan strap from sliding off the back, and that hit the trans tunnel. I cut the floor and put in a new panel for clearance. This car is a drag car only so I was not worried about the floor. The other area that is close is the pinch weld between the firewall and the floor/ trans tunnel. I trimmed it and welded the seam. Last you cannot get the upper bellhousing bolts in or out when the engine/trans is installed unless you cut some access holes into the tunnel/firewall, or they go in as one unit. You would also need the trans filler tube from Mancini Racing for this application.
