I want to order carpet for my 79 c30 with manual trans. How do I tell if its a high hump floor or not?

*87 chevy silverado* · 12-07-2010, 12:20 PM

any pics?

spudz · 12-07-2010, 12:23 PM

No but I will take some when I get off work tonight. I am PRETTY sure its s high hump but I dont want to spend 150 bux on carpet that I cant use.

Usually the higher hump will be squared off as well. Most non 3 on the tree manual transmission equipped trucks have the higher hump, IIRC.

If the shifter is on the floor in the factory spot it is High Hump.

Then a high hump it is... It looks like it. but just making sure... THANKS!

Easy way to tell, the high humps are bolt on, the lows aren't.

edit: Looks like that changed around 86?

The green one is a 76 Blazer 4 speed/205, the black one is an 82 turbo 350/208

My '84 K30 has a one piece floor, no bolts (wish it did

). Factory 454/TH400/205, cab-and-chassis if it matters...

Hope this helps,

The military CUCV K30s are high humps and are also one piece, no bolts.

Yep - very helpful.

Just to summarize: most 2wd autos are low hump, most manuals and 4x4 are high hump.

Gotta love the bolt on humps it makes it pretty easy to convert an auto to a stick

**Captkaos** · 12-08-2010, 05:22 PM

Not all high humps are bolt on.
Generally speaking...
all blazers were high humps. Autos were solid, manual were bolted.
all 1 tons were high humps. auto=solid manual=bolted
pickups sm465 (floor shift) equipped were high bolted 4x4 and 4x2.
Auto 4x4 were high and could be bolted or not.
Column shift were low tunnel
