looking for 4/6 drop flip kit

[sduckworth13]

I have a 1967 gmc 3/4 ton with leaf springs only in the rear ( no panhard bar or coils ). I am in the process of changing out the 3/4 ton suspension with a 5 lug disc/drum 1974 Chevy 1/2 truck suspension. I'm using my leaf springs from my 1967 GMC 3/4 ton, but using the 12 bolt rearend from the 1974 Chevy 1/2 ton. I called the famous ECE today and I spoke with a gentleman and told him that I was replacing my suspension using a 1974 Chevy 1/2 ton suspension and was doing a disc/drum conversion and I needed a rear flip kit for a 4/6 drop my 1967 GMC and he said that he didn't sell the rear flip kit I was needing for a 4/6 drop. I have seen lots of people post that they used ECE 4/6 drop flip kits on their 1967-1972 chevy/gmc trucks. Can someone please tell me the manufacturer that you went with and the part number I need. This picture is the underside of my 1967 GMC 3/4 ton
Thanks,
Scott

I PM'd him the DJM p/n info yesterday. Just in case others need this info....

Measure the width of your leaf springs. If they're 2.5" wide, get a 73-87 kit. If they're 2.25" wide get DJM's rear flip kit p/n FK 1012-5 for pre-73's.

I found the kit I needed. It is the Mcgaughys 33156 for the 1973-1987 Chevy truck. Here are a few pics of my drop.

Did you C notch the frame?? Ive talked to a bunch of people that say flip kits are great if you C notch the frame. Otherwise they dont ride very good.... Also are you going to mount a rear sway bar??

Reason I ask is because Im about to do the same think on my 72 SWB 1/2ton

[sduckworth13]

Sorry it took so long to get back with you, I didn't C-notch. But I agree that a C-notch just makes sense. I can tell you to also make sure you get the correct shocks because you will bang a nice long dent in your bed floor if you don't. My bed floor was banged up before i got it, but now I have a dent in the floor for the rear end smashing the frame.

Your truck looks great!
What's the plan for shock mounts?

[sduckworth13]

Thanks Keith, I appreciate the compliment. I was thinking shock extenders on the rearend so I could use stock shocks on the back and cross ref a front drop shock to a better quality shock brand. I really don't know what the best choice is though. I read some post where people use stock shocks. I also read that using stock shocks on a dropped truck will cause the shock to wear out faster and not give the maximum benefit of the shock. What would you recommend?

[lolife99]

I can't see the shock mounts on the rearend.
Are you going to have to weld some on?
The 73-87 trucks had one shock going forward and one shock going backwards.
The 67-72 leaf spring trucks have both shock going forward.

I'm sure you are going to have to fab new upper or lower (or both) shock mounts.

[sduckworth13]

I cut them off, they didn't line up. I am going to weld the shock mounts back on. I will have the drivers side shock mount on the back of the rearend and the passenger side on the front of the rearend. I hear it would ride better with that setup, and prevent axle wrap.

[sduckworth13]

Here are some pics of the rearend thats in in now. Looking at these pics, It appears I got a little overzealous and cut them off because someone said I would have to relocate the shock mounts. I believe they just meant on the frame. My previous set up had the shock mounts located towards the front of the rear end.

[hbchevy]

So were there any other issues with the front for instance. As far driving...speed bumps etc...

So, I've talked with Charleys Drop Shop in Portland, OR. He said there is absolutely nothing wrong with a flip kit for these trucks as long as u C Notch the frame. I was going to convert my leafs to Coils with ECE's kit. The price from ECE to lower the pickup 4/6 with the coil changeover was $1432 before freight. Charley talked me into leavin my leafs in the rear. He said it's a "Myth" about coils riding better than leafs when lowered. U just have to lower it "Correctly". Meaning C Notching the frame, flipping the leafs, and installing a new HD rear sway bar. I was quoted $1500 for 2-1/2" drop spindles, 1-1/2" drop coils, new HD sway bar, and KYB shocks up front. Flipping the leafs, c notching the frame, installing a new HD sway bar, and KYB shocks out back. That includes him doing all the work as well!!!! I thought that was perfectly reasonable.....
