Is the lower floor pan different between automatic and 4-speed cars? In the attached picture I have fitted a reproduction "hump" on the tunnel of an automatic car using a 4-speed console to locate the hump- notice the gap at the lower left corner where I'm pointing. Did 4-speed cars have a bulge here for shift linkage clearance or is this repo hump bent? The car is a 72 TransAm which will have a Richmond Gear 5 speed installed. Thanks

Might be best to install it after the installation of your trans.

It is possible that your "porch" has a tweaked corner.

Looks like you've done a proper layout.

You might want to double check your layout dimensions on another confirmed ORIGINAL factory 4 speed floor pan.

I can't say positively for early birds but when I installed my 4-speed hump from my 78 into my auto 81 it fix perfectly. It looks to me like that corner is bent up. I'll go check my hump when I get home and see if it is bent up like yours.

I am not familiar with a Richmond Gear 5-speed. That's why I suggested installing your tranny first.
If that is a repro hump, I've installed a few and have yet to see one that didn't need a little bend hear and there. It's easy to do. Nothing to worry about.

The Hurst shifter on a Nash / Richmond 5 speed can be mounted on the trans so it will fit through the original hole in the floor & factory console.

When swapping out an original 4 speed for a Nash / Richmond 5 speed,the console doesn't even need to be removed.

It's a SLICK install!

Ill get pics of a 4 speed hump on my 71. I think it goes over to the side further.

I just installed one of those a few months ago, and mine was winged out on one corner just like yours (the factory ones are not like that). Fortunately (?) it's made of steel about half the thickness of an original dog house, so it's easy to bend it.

Other than the dog house and the hole underneath it, the rest of the floorpan is the same between manual and auto.

BTW, you'll want to cut the hole in the floorpan tunnel almost all the way out to the weld flange on the dog house (same as factory). You'll need the clearance when installing the shifter.

Good to know. As always, 2many, you're knowledge is impressive.

Thanks all for the advice- I'll nail it down where it is. I want the new version Richmond 5-speed with overdrive; (http://www.richmondgear.com/NEW5withOD.html) and Summit says these are all on backorder, but it's physically the same size as the Nash/Richmond 4+1. I'm trying to finish cutting and welding before sending the shell out to be blasted.
