Re: cab differences
Isn't the location for the vin tag different as well as a vent for the gas tank on the 71-72 cabs. As well as the rear view attachment?

Re: cab differences
Yes, correct there are several differences if we are talking exact 67-72 year of cab. The original post was just asking for the: Difference Between 2wd And 4wd Cabs. Cb :bowtie

Re: cab differences
2wd will have a high hump if TH400 or 4 spd equipped. I believe ALL 4x4 have high hump. This part is interchangeable/ removable. I can't remember on the VIN tag location, I think they might be different. I think 71-72 started adding EEC (evaporative emmission control) to the gas tank, but this is not technically a "cab" issue, much like the fact that a true 67-71 cab will have three holes above the center of the windshield for the rear view mirror, whereas a true 72 cab will not. These differences would not interfere with swapping cabs from year to year.

Re: cab differences
TH400 does NOT include a high hump, unless it is a big block, or on the GMCs, a 1/2 ton with the V6.

Re: cab differences
Let Me Amend. Im Building A 71 3/4 Ton 4x4. I Used A 72 Cab. If I Use The 2 In Front Cab Mounts And The 4.5 Inch Rear Cab Mounts My Transfer Hits The Underside Of The Floor. Behind The Tall Hump.i Have Had To Install What Has Amounted To A Body Lift To Clear.
Im Running A Turbo350/np205 Setup From A 72 1/2 Ton 4x4.

Re: cab differences
You probably used the cab mounts from the 72, and I'll assume the 72 was a 1/2 ton 2 wheel drive?
On 3/4 tons, and 4X4s, and one tons, or any combo of the 3, the mounting point on the frame for the cab was lowered, so the body mounts (rubber) would be taller, and make the ride a little bit better. |

Re: cab differences
So how do you rectify this issue if putting a 70's 1/2 ton cab 4spd on a 4x4 71 3/4 ton frame?

Re: cab differences
Yup. The cab is the same, it's the frame that you are working around on this aspect.

Re: cab differences
this isn't pointed at anyone;
I am amazed at how often this comes up. Seems ones every 2 months or so, someone says "I thought TH400 came with a high hump". Where does this info come from? LMC has it right, and lotsa ppl refer to there catalog as the holy grail untill they log onto here. |

Re: cab differences
Was a TH400 really optional behind small block? In what cases? Heavy duty option or something? Personally, unless I was making ALOT of HP or towing a huge load, I see no reason for a TH400 behind a small block. I have worked on and parted out a lot of these truckas and never seen a TH400 behind a small block...

Re: cab differences
As I understood it the Turbo 350 didn't come out till something like 1970 so earlier trucks with a small block and an auto were either powerglide or TH400

Re: cab differences
Stingray has a good point. If memory serves, most pre 70 rucks I have seen have had PG's in 1/2 ton and TH400 in 3/4 tons, small or big block.

Re: cab differences
69 was the year for the TH350. If you wanted a 3 speed, you got a TH400, and you could still opt for the TH400 in a small block truck after that.

Re: cab differences
Was a powerglide used in 69 with a 307?

Re: cab differences
the powerglide was common in 67 and 68, but the TH350 pretty much took it's place in 69. I know Fine69 had either a 71 or a 72 out there at his place that had the powerglide in it originally.
