'63 Dart (maybe Valiant) firewall mod.

Anyone know if the wiper motor is attached to the firewall? I'm trying to figure how to deal with the hump the wiper motor uses.
It doesn't want to share space with a small block distributor
Someone posted that after moving the wiper motor, the linkage needed modification.
That doesn't seem like too big a challenge, compared with the actual "humpectomy".

Any more thoughts or ideas (and, yes, I've thought of a big block and a new hemi!) Thanks...
