Cpp C -Notch 60-62? #6372cnk HELP - The 1947 - Present Chevrolet & GMC Truck Message Board Network

bab59 · 05-18-2014, 12:15 AM

Looking to buy a C notch kit. Cpp has a part number "#6372CNK 1963-72, kit". The question I have is why only 63-72? Why would this notch not work on a 1960-1961-1962?
I have a 1961 C10 I am looking to notch.
Would it work on my application?

losthope · 05-18-2014, 12:56 AM

different frames , 63-72 had ladder bar frame and 60-62 has x-frame...ive only had 63-66 trucks so I cant tell you for sure why, but I assume the frame curvature on the 62 and under is different above the axle area where the notch would need to be installed...

losthope · 05-18-2014, 01:11 AM

heres a 60-62 x-frame , if you notice its pretty straight on the side rails of frame looks to be close to the same width all the way back to the rear frame :

and here is a 63-72 frame you can see they are totally different and that the ladder bar frame curves/tapers back in towards the rear so the rear frame width is smaller dimension width then the middle of frame and the c-notchs are made with this taper in them:

And that there is the reason the 63-72 notch will not work on your frame

heres a simple pipe notch in a x-frame

If a little notch is needed use 5" pipe to get where you want. Or PorterBuilt has big ones. I did 2"

LVPhotos · 05-18-2014, 08:06 PM

Ride height. Stock torsion front for now. Have PorterBuilt front crossmember to be installed.

That looks good. I have a 78 crossmember I am going to be swapping, and it has 2.5-3" Drop spindles. Did you box any of the rear frame in after the pipe?

What rearend are you using?

LVPhotos · 05-19-2014, 06:52 PM

The 62 frame is boxed in that area from factory. Bottom pic shows inside frame.

Boomscatty · 12-31-2014, 01:47 PM

Do you have any pictures of the inside of the frame after notch??

LVPhotos · 12-31-2014, 01:50 PM

It's a pipe. Solid and frame is boxed there.

LVPhotos · 12-31-2014, 05:31 PM

Zoomed in.

61_FL_Apache · 12-31-2014, 07:02 PM

I would only go halfway thru the frame with the pipe notch and also boxing it. I thought of doing this, but I pull a trailer from time to time and worry about the strength after a mod like that.

LVPhotos · 12-31-2014, 07:33 PM

The 60 to 62 frame is already boxed at that point. Used a 5 inch pipe and made 2.5" notch.

Boomscatty · 12-31-2014, 08:31 PM

How thick of pipe did you use?

amueller454 · 12-31-2014, 08:39 PM

i did this mod as well using 5" i.d. pipe. It was schedule 40 so 1/4" wall. I think it should hold up just fine

LVPhotos · 12-31-2014, 09:14 PM

3/16" I believe.

I don't own a 60-66 truck. But I have purchased many parts from www.pbfab.com for 67-72 and 73-87 trucks.
QUALITY PRODUCTS!

LVPhotos · 03-08-2016, 09:07 PM

The standard Porterbuilt arms will work with the adjustable links. I opted for 1/2 longer. The bags are Firestone 2500 but 2600 that are on front might be a little softer. Nate and Dave are great with answers.
I went 1" drop built in, there is a 3" as well.

I've heard nothing but good things about them. I'll definitely give them a call when I'm at that point.
