67/68 vs. 69-72 Rad. Supports and Brackets

[wancosc356]

I know there is a difference between the 67/68 radiator support and the 69-72 radiator support. I also know that the brackets that are riveted onto our frames are different too. I believe the 67/68 brackets have a smaller hole than the 69-72 brackets do.

Here is my questions:

1. Could u tell me the difference between the 67/68 and the 69-72 radiator supports? Pics would be best.

2. If I wanna mount a 67/68 radiator support to a 69-72 frame, what needs to be done? Do I use the 67/68 mount kit or the 69-72 mount kit?

Thanks

I am interested as well...TTT

while i can't answer your questions directly, I installed a 68 clip on my 72 burb, used the factory original rubber that came with the burb.

You are correct. The radiator support mounting pads for the 69-72 are thicker and also protrude out in the bottom of the upper cushion. This fits into the larger hole that the 69-72s have and keep it from moving around. WES

1. There is no dimensional diff. in the support itself, other then the way the head lites mount up and if you want to put an alum. 4 core radiator in it

2.The thickness of the core support mounts will give you problems, if you use a 69-72 mount on a 67/68. It raises the front clip, giving alignment problems with the door to front fenders. I think the 67/68 mounts are only about 1/2". You could cut down the 69-72 mounts, reglue the metal washer, to this dimension. Don't forget that is a torqued down dimension

Hmmm. Interesting. Glad it worked for u that easily. I hope mine will be the same way.

So can I put a aluminum 4 core radiator in it with a 67/68 core support?

So should I use a 67/68 mounting kit? Or do like you say and cut down a 69-72 mounting kit?


Anyone else ever done this? If so, howd u do it?

Yes, but there in lies the problem The 67/68 area under the rad. does not have a big enough flange to allow the rad. clearance to sit down . Minor problem, can be fixed with some cutting. If you have a 69-72 core support, look at that area, and will see it is much wider in that area.

I would modify,jmho, the 69-72 since they will fit better in the larger holed bracket

Ok. Well, hmmm. I dont have a 69-72 rad support to look at, but I will take your word.

Well in order to modify the 69-72 one, what needs to be done to make that work?

I'll try to take pics tomorrow, easier than explaining.

[jaros44sr]

Here's some pics. of the core support on a 67/68. My alum rad had a flange on the bottom that interfered with the core support

[wancosc356]

oh ok. I see. Thanks.

So in order to use a 69-72 rad support with a 67 grill, hood and fenders, what do I need to modify?

but, but ,but.... you didn't ask that at first!! Whole new ball game. Headlite buckets will be your biggest challenge, I'm guessing you have a chevy. You need to drill the spotwelds where the buckets mount to the core support, maybe about 6 for each bucket. Don't drill all the way thru, use a regular drill for starting the hole, (to get thru the sheet metal of the bucket) then grind the point off of a second same sized drill and use that to finish getting rid of the sheetmetal of the bucket. Then you have to make a square hole where your adjusters mount (2 per bucket). drill small hole for spring. If you are using the splash apron, that has to be worked on

Could be more mods., but I gotta leave for work...later

Wow! Seems like alot of work.

exactly, but you asked, and I answered! Easier to buy a correct repop core support...jmho

Well thats not the issue. The issue is that I have a 67 front end that I wanna put on a 71 frame.

Does this '67 front end have a rad. core support with it?

[wancosc356]

yes it does. it has a 67 rad core support. But I also have access to a 69-72 support.

Well there you go, everything should bolt up!!!

But the problem is that I am looking at getting a 69-72 frame, which has the bigger rad support mount holes.

[vegaschevy]

I may be wrong here, but I believe with the 69-72 frame you will need

67-68 fenders
67-68 hood
67-68 rad support
67-68 grill and parts
69-72 Rad Support mounts.

anyone can confirm this or tell me if youll need the earlier frame mounts

well according to earlier posts, the 69-72 rad support mounts are 1/2 taller which throws off the alignment with the cab.

Sorry I know this is an old thread, but its still not clear to me what is needed to put a 67-68 clip on a 69-72 frame. I've searched and I've found all different kinds of answers. Some saying the mounts are lower on a 69-72 frame so you use 69-72 mounts. Others saying use the correct mounts for the rad support. I have a 68 Rad support and a 72 frame do I need;
1, 67-68 mounts?
2, 69-72 mounts?
3, Modify a set of 69-72 mounts?

Thanks in advance.

Yes you need the 69-72 mounts. match the mounts to the year model frame and you will be OK.

Hey guys, I am dealing with this right now. I have '68 truck, but went with a new frame on my frame off restro. The thing I didn't realize till it was too late was the new frame was a '69-72. The only difference I have found is the size of the hole in the frame mount. The 67-68 had a smaller hole. I have heard that the mount rivited onto frame are higher on a 69-72, but in careful measuring between my old 68 frame and the new one, they appear exactly the same. So for my case, putting a 68 front end on 69-72 frame will be simply using the 68 core support mount, and making the hole in the 69-72 frame mount smaller. IE, welding in a washer or filling hole and re-drilling the smaller hole. Hope this helps..
