I am doing a 4 speed conversion on a 66. I'm not new to doing this, I did the identical conversion a few years ago, so I'm aware of all the parts needed etc. One thing I don't have though is anything that tells me about locating the hump correctly. Last time I did it, the floor in the car already had a hole in it for the auto console shifter. This time it's a column shift car so I start from scratch and I'm doing a very original 40,000 mile car. I want to get it right and do a nice job. Does anyone have measurements and pictures of correctly placing the floor hump?

I checked in the archives here and the resource section but I can't find anything about that exact question.

Thanks.

I found some help in an old post of mine from 6 years ago when I asked a similar question!

But if anyone has pictures of a bare 4 speed floor and some dimensions it would still be a big help.

I found this while searching the net for custom consoles.

Thank you, I did find that thread eventually. I worked on it today and that makes total sense. The specs given---

"Opening is 4-1/2" wide and 6" front to rear. The rear of the opening is 2-1/2" foward of the second sill plate screws. The top edge of the opening is 1" off center to the drivers side.
I took these measurements from my original 4-speed 66 Impala."

So that is what I did today. I didn't cut a hole yet though. I have a borrowed original hump that I used to mark it. Now I am waiting for my repro hump to arrive (and I hear it won't fit as well, but at least I know where it has to be located now and I can make it fit.)

Leave plenty of metal for overlap. Every factory floor cut under the hump that I have seen looked like it was crudely cut with a torch of some sort.

Just curious. Two things, can someone advise: is the style of hump (shape/design) the same for both console and non-console applications, and is the floor location the same for console and non-console applications?

Yes, they didn't do a nice job cutting them. Chevelle and Nova are the same way.
