Low hump or high hump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 63' has a big block and a Muncie 4 speed. I'm considering switching to automatic and became aware of different humps.

Does 63' have a low hump and high hump options?

How would I tell what I have?

If I switch to a 350 trans would I need one or the other for clearance?

I beg to differ, you have a 3 speed column shift or Automatic Hump, See how it curves back up at the seat.

The four speed High Hump goes almost level from the front to the seat.

It was originally a 3 speed column shift

Ah ha! My knowledge leaves something to be desired. My appologies.

OK, it appears I have a low hump. And I saw a couple posts that a 350 tranny will fit?

Here are a few pictures I pulled off the net that should make identification a little easier. A high hump pan is almost square in the center, rises up in front of the seat, and is always removable:

The low hump drops in front of the seat, may be removable or may be a permanent part of the floor. From all the threads I’ve read on this topic, they are not directly interchangeable, however a high hump can be added to a low hump truck if the portion from the high hump donor truck in front of the removable pan is also cut out and welded into the low hump cab.

Does anyone have a spare removable low hump kickin around?

**aerotruk63** · 10-30-2011, 11:54 PM

I believe it's a year issue. My 63 has a removable low hump but the black 66 that I sold had an integrated low hump.

I was searching to find out what type of hump is in my truck and discovered a pic prior to me owing my truck was used as an example. Where did you find that high hump pic Markeb01?
