Factory Manual Car to Automatic floor shifter location

Hey guys,

I recently decided to go from a four speed manual 833 to a 904 trans in my duster. I would like to put in a Hurst quarter stick for the shifter and was wondering if i am able to use the factory hole from the manual transmission or if i have to weld that hole shut and relocate the hole for the new shifter??

Anybody ever put an automatic transmission in a factory manual car?????

Thank you in advance for the help!!
