4 Speed Hump

I had the auto in my 67 barracuda and converted to a 4-spd.
The reason for the hump is because the shifter linkage needs to ride over top of the subframe crossmember.
It can't do that with the original floor pan there.

The hump comes with a cut out template that you use as a pattern for cutting out the floor.

Then you can weld the pan in place after you cut out the floor with a whizz wheel or a plasma cutter, but it's better to mount the trans and linkage to make sure you have the pan positioned correctly, then tack weld it in place before you go psycho with the welding wire.

I used a whizz wheel and it took a few hours to do.


I got mine at Sherman auto parts for about $95.00 with shipping 4 yrs ago.

The rear portion of the hump is universal for darts and barracuda's and it fits some cars better at the rear of the hump.

I need to add a little more sheetmetal to my hump to cover a 1/2 inch gap at the bottom rear, some guys use heavy seam sealer or body filler, but I'm gonna use sheet metal for strength.

I did hear that Keislers humps are perfect fit, but make sure first.

Oh , don't forget to install your drivers seat in your test fit procedure as well.
