Help! 78 Chevy Front End under a 67? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

c10ss69 · 06-27-2007, 10:56 AM

New to the board. I need some help. Have any of you put a later model front end under a 67-72 truck. I bought my daughter, who'll be 16 in Dec, a 67 SWB w/drums and I want disc brakes up front. A friend of mine donated his '78 chevy so I could swap the entire front craddle into the 67. Don't know if it'll work. I know I can go to the junk yard and get parts from a 71 or 72 but these parts are free and they are working. Thanks in advance.........

Anything is possible with modifications, but the frames are different widths.

c10ss69 · 06-27-2007, 11:20 AM

I have to many other project to fab this thing in. I have until dec to swap the 3 speed to automoatic, build a motor, body, paint color change, carpet, new bumpers, disc brakes and swap the rear to 5 lug and I cant start it till Aug. Thanks for the info................

This is actually a very common swap. I have one on my '68 that the p.o. did. If I recall correctly there are 4 bolts, two of which have to be redrilled. Very easy swap. However I would suggest for simplicity sakes (if you ever decide to lower the truck) that you get the 1 1/4" rotor setup so that you can buy drop spindles. I haven't found any yet that are made for the smaller 1" rotors. Use the search function and check the FAQ section and I'm positive you will find the directions. Hope this helps!

You can swap the entire crossmember in place by re-drilling a few holes or just use the newer a-arms, steering linkage, & brake parts w/the original crossmember.

dave2953 · 06-27-2007, 12:42 PM

with Scoti. I left the crossmember out when I did my swap and used the upper/lower a-arms and steering component, etc. It's a pretty straightforward swap. Keep us updated on your progress and post some pics of your truck if yo can. oh yeah,

to the board!

Not to steal the thread but..

Does that work with the 3/4 ton as well?

It's a bolt in deal by redrilling one hole and enlarging another. I have done two of them.... Be sure and use the stiffeners that are inside of the later frame.

here is a pic of the holes that need modified.

I agree with searching the FAQ's on this one.It will work just read all the info so you are armed with KNOWLEDGE!!!The later front end parts(Ball joints,etc.) are also cheaper.

It should.

Negatory ghostrider, they're the same width.

68chevy68 · 06-27-2007, 10:30 PM

I put an 84 front end under my 61 and only had to drill a few holes as stated above.

You don't even HAVE to use the newer A-arms. Just make sure the ball joints are the proper ones for the spindle. I'm just putting 72 spindles in my 68 with 72 ball joints.

Are you using outer tie rods from the 72 and adapters for your factory inners? I don't think your factory outers will work with 72 spindles.

True. The only reason I included them is they have bushings like a car so they offer a 'better' ride vs. the original pre-73 rubber-lined steel shell.

how would one know short of pulling off a wheel and measuring, what rotors it had, I have been thinking about buying an 87 chevy to donate all the front end parts to mine. The truck is about an hour away, and hate to waste a trip if is the wrong thing.

dave2953 · 06-28-2007, 01:04 AM

I think there may be a code in the glovebox. Maybe someone could look for you and see which one it is. JB3 is 1" and JB5 is 1.25. I'm pretty sure this is right; someone please correct me if I'm wrong.

Ah Ha, they're different widths at the cab mounts and not the front suspension? I see. Thanks

redrum, yes it works fine. Same as 1/2t. This is a pic of my '70 frame with a '91 crossmember and steering. All parts 3/4t

c10ss69 · 07-02-2007, 07:43 AM

Thanks for all the info. I'll post pics of the build when I get it started.

c10ss69 · 07-09-2007, 09:24 AM

Here's the 67 I bought for my daughters 16th that I'll be starting on next month. This will be a 4 month build to be ready for her birthday in December. I'll post pics as I go......

krue · 07-09-2007, 09:40 AM

Looks like a solid start. What're the plans?

c10ss69 · 07-09-2007, 01:51 PM

The plan for now is changing it to 5-lugs w/disc brakes, 3-speed to an auto, has to have a new motor, new bumpers, grill inserts, new light bezels, relocation of the gas tank, vintage air and new paint inside and out. She wants it electric blue pearl so I'll probably paint the inside a soft silver.
