c notch on a stock frame
hello, Im new at this restoring thing I bought a 70 snb truck about 4 yrs ago and have desided to start a frame off resto, how ever I have never been this deep into a project before, so here is what I have done to the frame so far...
I bought a 4/6 drop from Early Classic, a 5 hole disk conversion with 2.5 drop spidles, I have been told that i will need to notch the rear frame, so i went to my uncles weld shop and found some scrap 6 inch oil field pipe to weldinto the frame, but I have now Idea just were to make the cut. So this is what i have done in an effort to estimate the spot to cut... I took the springs out of the rear and with the rear end still bolted to the trailing arms, I allowed the frame to rest on the axle tubes and scrabed a line on either side of the tube on the frame... So my question is will this be a reasonable place to make the cut? Any and all help will be welcomed please help!! note the pic in the avitar spot is a hope and dream of mine someday. |

Re: c notch on a stock frame
Although its debateable Id say ya need one....my 67 daily driver bottoms out with a 6 inch rear coil....almost daily. Not only do you need a notch...it would not a bad idea to run an adjustable pan hard bar....EDIT My 67 is a LWB and i baught my drop kit from McCoughys....they are one of the best for static drop kits for 67-72s........

Re: c notch on a stock frame
I guess Shane i am thinking from a LWB experiance...im not shure of the added weight a lwb is from a swb ..but from the 3-4 trucks that i have lowered with coils (all of which were lwb.s) they all needed a C-notch.....that is with a 6 inch coil...drop....not trying to step on any ones toes....im just trying to help the dude.....Sorry Shane if it came off wrong.....

To answer your question, yes (as bglad420 said) that is where your housing would hit if it bottomed out so that is where the pipe would weld in. LockDoc

![]() Anywhoo ... I've had good luck with the 4/6 ECE kit (springs, spindles, shocks & relocators, and super trac bar) without a notch on a couple of SWB (2 different trucks - 1 mine the other a friends). You are probably right about the LWB having additional weight and needing one, I've never worked on one so I can't say one way or the other. Let us know how it turns out Matt ... we need pics! ![]() Last edited by Shane; 02-25-2008 at 07:22 AM. |

Re: c notch on a stock frame
I just learned this, if you are interested in running a "Super Trackbar" on the rear
you will need 4" springs and 2" blocks cause the bar will interfear w/ the c-notch.
