High hump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Can you tell from this picture if this is a high hump floor?

It is a 70 GMC 3/4 ton with a small block and a 4 speed.

Is there a common fomula for what came with a high hump?

Which is more desirable?

Yes it is a high hump. Pretty sure all manual transmissions had high humps.

Where in the he!! is the clutch peddle?

**seafoam68** · 02-11-2010, 10:22 PM

My '68 was a manual, "three on the tree" and it has a low hump. From your pic it seems like it is a high hump. If that is bolts around the base of it, it is.

Just to the left of the brake pedal!

It is down on the floor, you can just barely see it on the extreme left edge of the photo.

Yes its a high hump, the low hump was molded to the floorpan, the high hump was bolted, and ya the clutch pedal is barely visible.....

i thought the high hump only came with manual trans. i know i saw a thread on this......

high humps;
all 4X4 trucks
all 4 speed trucks
all big blocks with automatic

Those are the only ones that were supposed to get them, but an odd ball went down the line from time to time with a high hump.

I have even run across a truck that was 402/TH400 and had a low hump in it

JHT67 · 02-12-2010, 10:56 PM

My 67 is a high hump, and per the VIN = 6 cylinder, 3/4 ton, also has the column shift. Also has an odd model type in the VIN, it's a 9, not 4,6,or 8. Look up your vin just for kicks, or you may find something diff about your truck. BTW didn't help me though cause I still don't know what the 9 means for my truck.

Longhorn Man · 02-12-2010, 11:38 PM

JHT... whats your VIN? Also... what part of Columbus you in?

JHT67 · 02-13-2010, 12:00 AM

Longhorn Man-the VIN CS297B145888. I live on the southside, just north of Southern Pines=23 s./270 area.

Longhorn Man · 02-13-2010, 12:22 AM

I'm thinking a 9 model is a cab/chassis... maybe a flat bed. I'll have to dig into my books tomorow if no one can confirm/deny.
rt 23.... by the old K-mart, right?

JHT67 · 02-13-2010, 12:32 AM

Longhorn-- Yep borned and raised,( not in the old k-mart though) you always been in Hilliards? I kind of thought some kind of work truck/tow truck, but LMC was all the VIN help I could find, it'd be really cool if I could find out what the 9 is, thanks for lookin'

Longhorn Man · 02-13-2010, 07:37 AM

I actually just moved here a few months ago. I was at Rikenbacker for a tick in highschool then on the west side for a long time, left here (7.5 years US Army) and came back to the west side in 01.
I'm out the door right now for a loooong day at work... I'll try to look that up this evening.
I raced twice at the BMX dirt track by the K mart back in '90 or so... maybe '91.
