Duster Shifter Clearance

Could anybody help me out with this? I am replacing the floor pan and 4 -speed hump in my 70 Duster.I removed the old hump and had to repair the Torsion Bar-Crossmember where the shifter goes.Apparently some Do-Do went bezerk with a sawzall .I guessed at the rearward flange on the mount is supposed to be continous as the front is,but part of me thinks it should be notched a little to facillitate shifter clearance.The area in question is indicated by the Red arrow between the Red marks.Can anybody verify this that has a Duster also????????I would think all Duster,s 70 through 76 should be the same.Thanks...Jeff

Yes, you are correct that area needs to be trimmed. Hope this pic helps, its my 71 Duster 340 4spd and you can see that the "flange" is trimmed. If you need another pic let me know.

A few more pics please.....Thanks...Jeff...

I took the floor hump out of a factory built 72 duster many moons ago and the Tbar X member was cut out just like the one the OP fixed ...
