First off, manual trans is a different ball game. Addon floor hump for shifter required.
For automatic, OEM floor pan is stamped for center of a large hole where the shaft goes through and the 3 smaller holes for boot attach screws.
The floor pan is not marked where automatic shifter stand and the 2 console mounts are welded in. There once was a template, available from a member here, to properly locate those parts. I dont know if that is still available today.
The only good part... The holes in brackets for 4 console mounting screws are slotted. If they are welded fairly close to where they belong you could smack the heck out of them with a hammer to get them closer. They do need end up pretty close. Forward to back so shifter reaches park and low is a given. If console is skewed left or right the sliding blind in the console will not survive long term.
A note about that large hole for automatic shifter down rod... I didn't own a hole saw that large. I figured out how to geter done with what I do have on hand. 2 holes. So the hole beneath my floor shifter boot looks like a 8 or more like a 2 ball snowman.
one more note... In years to come you will discover the conversion was a lot more trouble than it was worth. The OEM console with no cup holders and no arm rest is nothing more than another glovebox that requires more cleaning.
