K30 frame question

[rs74]

Is a regular cab K30 dually frame the exact same as a single wheel regular cab dually. Possibly thinking about doing away with one of my cab and chassis frames and swapping some stuff over to a pickup frame. I would need to get the wider rear axle. I just want a K30 dually pickup. Been lookin at http://www.car-part.com/ for a frame since I can't find any locally. They don't list whether it is a dual or single wheel frame though.

I used a SRW K30 frame from a CUCV to replace the rotted frame on my 83 K30 dually. As long as they are both pickup frames and NOT Cab/Chassis frames they are the same.

Thanks. That is what I thought but wanted to confirm that. Trying to find a frame may be harder than I thought. I already have one C&C K30 and would like a pickup dually K30 too. Then all I will have to do is sell the C&C frame.

What's different about the C&C frame ....length?

Yeah mine has something like a ten foot rear frame section behind the cab. Not sure if the frame rails are different widths or not.

Widths are the same, I compared with my K20 , 34 inches.

But like you said the difference is the length between the cab and rear axle.
I was wondering if they made a C&C frame that was the same length as say a dually.

I want to say that the closest one they make is 4 inches longer. The pickup is something like 56 inches cab to axle 131.5 inch wheelbase and C&C is 60 inches 135.5 inch wheelbase. The one I have is either 159.5 or 164.5 inch wheelbase. I could shorten the frame but then there is no frame rails after the rear spring hanger and some would have to be added I think.

I have some frame rail after the rear spring hanger...

They must have made a bunch of different ones, never seen or heard of a frame that ended at the rear hangers.
Here is a pic of mine from a while back.

Someone has hacked on the frame back there before I got it. I was told it used to have a welders bed on it so who knows what they did.

I went out and was looking at the frame thinking about going ahead and shortening it. It only lacks a few inches at the very rear of the frame so I think one could get by with that. However, there is not any provisions in the frame for shock mounts on the outside of the frame since C&C's mount on the inside of the frame. That and I don't know if a truck bed would set on the frame the way it needs to. It might just don't know. Anyway it was a thought. I have an email in on a frame but it is out in Massachusetts and I am in Illinois.

Some of the frames are cut back close to the spring hangers for the pivot point if there is a dump bed for instance. Here is a Pickup fear frame (m1008 CUCV) and my dump K30 C&C

Here's my 1990 V3500, single real wheel. Shocks mount inboard just like yours. you can see the left shock mount on the frame, forward of the axle with no shock on it. I would find someone parting a truck and get the rear tails of the frame and have them welded to your frame to make it the correct length to fit a bed. That is what I had to do to mine due to the ends of my frame being damaged by a bumper being welded on.

[rs74]

Well shoot, I thought the shocks mounted on the outside of the frame for pickup frames. I was under the assumption that only the C&C trucks mounted on the inside. IF I cut the frame down I will have to cut out two feet right behind the cab in order for everything to line up.

Stretch the bed.

My dad was a pipeline welder. He build beds for all his trucks. He always shortened them down some for easier manueverability in tight spots and to make it easier to work off the back of the truck.
