Did the stock 1967 c-10 custom or any cab for
that matter have a floor shift? just wondering
if the patched hole in my floor is stock or not

BAGNDRAGIT · 08-04-2009, 11:49 PM

mine came with a 4 on the floor, so i assume it was standard. what trans is in it now??

got any pics???

67 c10 guy · 08-05-2009, 01:40 AM

no pics of the plate but its almoston the edge
of the hump(drivers side) and further back.
curently has a turbo 350

BAGNDRAGIT · 08-05-2009, 01:47 AM

that sounds like it might be a 4wd hump, is it a low or high hump?

im pretty sure 4wd is the high hump and 2wd is the low hump. if im wrong someone will correct me....

There was no floor shift on these trucks. That had to have been added by a previous owner.

I have a factory installed Muncie M-20 floor shift in my 70. I can prove it with my SPID. If the hole is to one side it probably is a High/low range shifter for 4WD.

67 c10 guy · 08-11-2009, 12:40 AM

the truck is definitely a 2wd no doubt. i find no indication of
it being a 4wd. Whats the height diference form
a hi hump to the low hump? How do you look up the spid?

Thanks for all your help!

Well then I stand corrected! That's a new one for me as I've never seen or heard of such an option either in the factory lit. or on any truck. Must be super rare.

Just because you hadn't heard it, doesn't mean this wasn't a common item. IIRC all 4 speed manuals got a floor shift. Most of them (I don't recall the model number) had the Granny first gear so in effect you drove it like a 3 speed. I think you'll find these more common in 3/4 and 1 ton models, since the Granny first was good for pulling a heavy load from a stop.

That's right Chevy_mike. My Muncie has a granny low and you start up from a stop in second gear.

The 4 speed was the base mode tranny in all one tons regardless of the year. (67 - 72)
It was pretty common in all 67 - 72 2 wheel drive and 4x4, 1/2 ton and 3/4 ton trucks. Not even rare.
The SPID is the sticker inside the glovebox door that tells you what options the truck had originally
Your TH350 is not original, they werent installed till 69
the high hump floor is bolted in, the low hump is part of the stamped floor. All 4x4 trucks, all 4 speeds, and most every big block/auto got the high hump.

Sorry,I thought we were talking about an AUTOMATIC trans with a floor shift!

I picked a bad week to quit coffee.

That was only when you had the infamous "corvette option"

Sorry guys I couldn't resist that one.
