I would up just bending it to fit in the end for now.
Attached are the pictures of the factory TBR7 shifter after I bent it back into place and IMS bent into position too.

The IMS is definitely thicker.
Also, the stock shifter has a long shaft with a bolt that catches in a groove, where the IMS just pressure tightens on the end of the shaft.
Anybody have a link for a shifter that fits without bending it and has the proper shaft fit?
