Cab mount question
I have a 70 2wd lwb that I am going to be swapping onto a 68 4wd frame. When I took the cab off of the 2wd drive frame this weekend, I noticed that the cab mounts were different than the 4wd frame. The 2wd mounts were flush with the top of the frame, and the 4wd were about 1" - 1.5" below the top of the frame. Is this a normal difference between a 2wd and 4wd frame?
I would like to know if I need to do some mods to the frame before I stash the 2wd frame in storage. Thanks guys. |

Re: Cab mount question
The 2wd 1/2 ton use different mounting than 3/4 ton 2wd and all the k series (4wd).The cab will go on w/out mods.Just specify when you get cab mounts that it is for a 4wd and that will get you the right rubber mounts.The 2wd ones wont work.So,that's what you need--4wd rubber cab mounts,that's it,And also a "high hump" floor if you dont have one already in the cab

Re: Cab mount question
are the cab mounts the same on a 2wd 3/4 ton as a 1/2 ton 4x4?

Re: Cab mount question
I thought so. my trucks aren't stored at home and I didn't really pay attention to it. I looked at the pictures I have and they do look the same.

Re: Cab mount question
If it has an auto trans the cab will clear everything alright without the high hump.
I've seen one without the high hump(not my truck). I also just sit my cab on the frame and it seems to have worked. I'm still going to cut it out and put in a high hump just in case I ever need to swap engines. Without it I don't know how you would get to the bolts. |

Re: Cab mount question
If the T case is to be installed the high hump will be needed.

Re: Cab mount question
I can take pictures if you would like. I have a 1/2 ton 4x4 with a cab bolted to the frame. No high hump. I haven't cut a hole for the shifter yet. It has a 350. with an auto trans and transfer case. the engine trans and transfer case was on the frame before I put the cab on it. Here are the only pictures that I have

Re: Cab mount question
is the hump in this truck higher than a normal low hump cab? Have you guys tried to put a low hump cab on a 4x4 frame and it wouldn't work? I'm wondering why mine worked but it looks like everyone else has a problem with it...I will be installing a high hump so I have access to the trans bolts in case i ever have to change it. besides it is correct to have a high hump so i'm going with that sit up although I don't HAVE to.

Re: Cab mount question
Thanks for the input. Glad I wasn't just imagining the difference. I did score the high hump out of the donor truck. I have already cut the hole in the 2wd cab. What should I use between the two panels when I bolt it down to keep the water and grime out of the cab?
