What hump do I have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's a 66 C20 with granny 4 speed on the floor.

I stripped the drivers floor over the weekend (it's in a lot better shape than I thought) and I noticed the hump is bolted in. Are all '66 C20's bolt in humps? How do I know if it's the high hump or not?

Here's a shot of the floor after I washed it and before I stripped it.

What should I look for to know what hump I have? I need a high hump for the dropmmber. Thanks.

You have a high hump. The way you can tell is that it is bolted in. The reason you have a high hump is the 4 speed. A 3 speed C20 would have a low hump.

Thanks, Ray, that is awesome news for my budget. One less thing to buy!

Here's a thread that clearly shows what a high hump looks like with the covering removed:

And post #11 on this thread has comparison photos of both low hump styles, the one piece type and the bolt in version. Details are a few posts earlier:
