Trans Hump Height

Anyone know, off hand, if the tranny hump is higher in an F100 with a C6 than in a truck that came with a three on the tree. The hump in my 67 doesn't even have a removable top, and looks to be quite low. I intend to install a C6 behind a 390, and wondered if I was going to have to modify the hump.
I appreciate any help you can give me.
Thanks, Brett

All the C6 bumpside trucks I've seen have had a removable hump. It's the same height as a 4 speed hump minus the shifter hole.

Oh, and yes it is taller. I'm told a C6 will fit but requires the hump to be massaged with a large hammer.

I've been lucky, my were all automatic and switched to stickshift, so they had the hump and not needed.

My '69 was a C6 truck and the hump in it is quite taller then my '67 MX was. I have to look, as can't remember if '67 comes out? Been too long since I looked under the carpet.

I don't know what determines the hump size? Year/tranny?

I'm thinking it's the trans that determines the height of the hump. My 67 has an MX and the hump isn't removable. My 72 with a C4 is the same. Last year I scrapped out a 68 F250 with a C6 and a 72 F250 with an NP435. Both had removable humps.
