Ok ill just keep,it simple and stay with the 5 lug front and donor rear end .. Since its 1.5" wider will my tires still be inside of the back wheel well ?

That depends on what size tires and wheels you run on the back. You will just have to choose those accordingly to the room there is available. There are many guys here that run the wider rear differentials. You might try a search to see what backspacing those guys are using. I'm thinking you will need 3.750" +

Wheel backspacing. Of course this depends on how wide of wheels and tires you are wanting to run.

Well I read through the thread, and maybe I missed it....Will 66 control arms accept 71-72 ball joints?

[Captainfab]

Yes they will as long as you stay within the same series. By that I mean C10 ball joints in C10 arms, C20 joints in C20 arms, etc. In fact the ball joints thru '87 will fit the '63-'66 control arms.

[LostMy65]

I was wondering if the brake calipers off my 79 1/2 ton 4x4 suburban are the same as the 2wd calipers?

[Captainfab]

Yes those are also D52 calipers.

[LostMy65]

That is good to know.

You can also buy rebuild kits for them, and rebuild them yourself if you want. They are not expensive to buy already rebuilt, but every $$ counts.

hey captain fab you wouldnt know from the top of your head a thread thats shows a rear end swap like the one im going todo on my 65 gmc?? the rear end is coming from the 77'' donor. its going to be my first swap and i wanna know what to look out for u know what measuremnts i ned to look out for but my original mounts were my leaf springs are bolted are rusting out were could i find some were i can buy them??? im going to keep the 5 lug bolt pattern.. thanks

this forum rocks !!!!!1

[Captainfab]

No I do not know of any threads here on swapping the rear ends. If the leaf spring mounts on your original rear end are rusted, that shouldn't matter since you are changing the rear end. Or are you talking about your U-bolt plates? If so, then just use the ones from the '77. The '77 rear end will bolt right up to your leaf springs. Really no measuring required. The only thing you might have to measure is when changing your shock mounts.

Ok sounds simple.. Well heres the pics to,show you what im talking about : ) I dont know were to start looking for them .. Just to be right what bolts up to the leaf spring and then to the mount to the frame (what im looking for) is the shakles correct.

OK, so it's your spring hangers that are rusted, and not the spring perches, like I thought you were talking about. Is it just that one hole, or are they basically completely rusted? If it's just that one hole, that should be able to be welded. If they are completely rusted, you will need to replace them with good used originals. I'm not sure just what all years will interchange. You might try looking in the 60-66 classifieds here on the forum. If you want to post a WTB, you will have to become a suporting member to do that.

[rudy350]

If you can't find some originals to replace those, you might consider using the ones from the '77 donor truck. You might have to change both front and rear hangers along with the springs. I can't say for sure, but it is an option for you. You will just have to make some comparisons between the 2 types and see exactly what would have to be done.

Subscribing, need to go back to page one, and read through...
great thread, thanks for all the effort

[Bkndsdl]

Guys, I did some writeups on my original website about how I did my swap. I used a '75 truck as a donor. I bolted the crossmember up and washed all the brackets off the '64 rear and welded them on the '75 rear. Here is the link:

Hope this helps!

so i have a 66, i have an ece 4/6 drop spindles and all. can i get the control arms off a 73-87 and bolt right up to my suspension amd use balljoints for a 66? will steering still be the same for 66?

[Captainfab]

I am not familar with what ECE offers in dropped spindles. You need to contact them to find out what ball joints and tie rods to use with the particular spindles you have. Then you will be able to determine if you can use the '7-'87 lower control arms, and if the '66 tierods will work.
