rear end ????? feedback asap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

bigstoys · 01-19-2006, 07:47 PM

does it matter what time of rear suspension your rear end came out of???
here's the senario... 67 with coils wants to put a 71 rear end which had leaf springs... will it work???

dwaite72lnghrn · 01-19-2006, 08:38 PM

You will need to weld on the bracket for the coils, as the leaf spring brackets are different.

**dennislbrooks** · 01-19-2006, 09:32 PM

If you are putting the 71 in a 67, maybe you just need to compare the perches and move as necessary. This should be a possible swap. May be easier just to find a 71/72 that came from coils.

cdowns · 01-19-2006, 09:36 PM

i don't think the leaf rears had panhard bars so you'd have to weld bracket for that also

**special-K** · 01-19-2006, 09:50 PM

Swap the internals between the housings?

**dennislbrooks** · 01-19-2006, 10:16 PM

and re-use the 67 6 lug axles? --- should work

JRB · 01-19-2006, 10:49 PM

Why are you doing the swap and what kind of differentials are they? 12 Bolt Chevy? 10 Bolt Chevy? Are you looking to change the ratio?

**Palf70Step** · 01-19-2006, 11:10 PM

If your looking at swapping internals, like axels, the 72 axle is a bit wider. I think about 3/4". But you should be able to swap out center sections if you just want the gears out of the 72.

**special-K** · 01-20-2006, 08:34 AM

It`s a`71.

bigstoys · 01-20-2006, 11:13 AM

the 67 has the disc brake conversion which is now 5 lug and the rear is the factory rear 6 lug. we want to buy rims and what not and it's just easier to buy all the same lug pattern ie. tire rotation, blow outs. i think the factory rear is a 10 bolt and the new rear is a 12 bolt posi with 3.73's. so we have to cut brackets off of 10 bolt and re weld on 12 bolt.... am i correct.

Longhorn Man · 01-20-2006, 11:14 AM

71...still 3/8 inch wider.

67ChevyRedneck · 01-20-2006, 11:28 AM

OR, you could do what I am planning on doing. I can't seem to find a good coil spring 71/72 rear-end, and I too, have a 5 lug disk brake set up on my truck with a 6 lug rear. Early Classic Enterprises sells 6 lug front rotors that will work on your truck. They are about 180 bucks for the pair plus shipping. Just a suggestion....

The rear ends I have found around here are like $250 and well used. Make sure when you cut/weld the perches that you get the angles correct on them and that they are straight and square. It sucks when you burn through a set of rear tires after only 10K miles

Longhorn Man · 01-20-2006, 11:49 AM

2 bills for rotors?!?!
I used to push those for them for the same reason you are bringing them up... but man, 2 hundred bucks.

67ChevyRedneck · 01-20-2006, 12:05 PM

Andy, that's just what I've seen in their catalog, I think $89 each? If you know where I can get them cheaper I would be much appreciative. I only paid $70 for the pair of 5 lugs I got from Advance Auto.

Longhorn Man · 01-20-2006, 01:10 PM

I know it differs from junk yard to junk yard, but around here you could get a whole rearend for less than 100 bucks... it's just a matter of waiting untill one comes through...esp if you want a particular gearing.
Have you contacted local machine shops to find out what it'd cost to have your axles redrilled?

67ChevyRedneck · 01-20-2006, 01:55 PM

The yard's round here must have all gotten together and agreed $250 was the going rate. I went to 4 near columbia (SC) and they all wanted $200-$250. I'm not a big fan of redrilling axles. As far as rims, I'm going with a brand new set of white spokes so 5 or 6 lug won't matter.... I'm going back to Cola this weekend, might be time to check around again.....
