Hey Mac67 I live in joliet Il, i have a few ? for ya. I've read before in four wheeler mag that only 1 ton axles are a direct bolt up to our trucks. I cant attest to this being true though cause i've never tried. Do you know if its true. Can you measure spring perch to perch. What axles are they. Dana 44 front, 12 bolt rear? I could be interested if it has the right rearend. Thanks.

[MAC67]

4 wheeler mag is off theyre rocker, if that was true then the 3/4 ton and 1 tons would have different perch widths , 1/2 ,3/4 1ton axles will all swap out under any chevy truck , these are the corp10 3/4 ton front with the 14 bolt ff out back , dont believe everything you read lol ,,the only difference really is axle tube size , well thats the only real difference whay it wouldnt bolt with youre old stuff , you would need some bigger u bolts , and an adapter ujoint posssibly , im not really for sure , ive needed them on some swaps and didnt on others

Hate to tell ya this, but the spring perches on my truck ('72 Blazer) are closer together than the perches on my friend's '76 P/U...

from Pirate4X4.com
1-tons feature 40.5" perch spacing - whether C&C or pickup, whether SRW or DRW. 3/4-ton is 42.5" spacing

http://www.pirate4x4.com/tech/billav...ble/index.html
about halfway down the page, in notes, beneath the 'specs' chart

1 tons have different hangers, IIRC. Get a tape measure, and see for yourself...

still no big deal to relocate the perches...

I dont, believe everything i read! Expecially when i read that a truck has a 10 bolt & a 14 bolt. Maybe, but i would imagine it would have a D44 front, depending on the year, & maybe a 12 bolt. My spring perches are 40" apart center to center. I would almost bet a plug nickel that the subs are further apart than that. I'm not rippin ya man, If you can check center to center for me & prove me wrong then I may buy it. & oh yeah I'll then give you the plug nickel lol. Let me know.

[MAC67]

lol , well pal , any 3/4 ton chevrolet pickup built from mid 76 to 87 has a 10 bolt front end , trust me on this , ive gone through wayyyyyyy to many of them to be proven wrong , im not youre average truck guy , i have been through these older chevy trucks with ia fine toothed comb a hundred times over , mainly the 73-87 , there wasnt a 3/4 ton chevy pickup that came with a 12 bolt , the dana 44 was offerd as a half ton and a 3/4 ton pre 77 , and the perches are no farther apart , the suburban , blazers and pickups all have the exact same distance for axles, common sencs will tell you that since these trucks were all built on an assembly line and it would not be cost effeiciaant to change these axles around for each style , i know im right know you prove me wrong and send me the plug nickle

the 70s are over man, move on to the 80s. 10 bolt fronts are normal, Dana 44s are ancient history. all straight axles from 73-87(91) will bolt directly in (Dana 44/60/Corp 10). rear axles are the same widthexcept for 1 tons.

[MAC67]

toddol , you need to get into them and do some research , im not bashing you by anymeans , just do some research on them , hell i was new to it once to. i will admit the dana 44 is a better axle than the 10 bolt IMO , but i have seen alot of the 10 bolt fronts take a heller beating , if im not mistaken look at the front of youre dana 44 , it has 10 bolts in the cover , theres youre 10 bolt , the distint difference that i pick out a dana 44 with is at the bottom of the punkin a dana 44 is pretty smooth where as a corp 10 has 2 dog ears on either side

[MAC67]

also hate tank i have also personally pulled a setof 3/4 ton axles from a 74 3/4 ton truck and slung them under a 70 blazer for a friend of mine years ago and they bolted right up in place of the original blazer axles , just my expieriance , done her a bunch , took a set from a 76 chevy 3/4 ton and put them under a 67 factory short fleet 4wd with no modifying , there is no difference , now the one tons i have gotten i always left the axles in the k30's so i am not quit as familiar with swapping them out , i do know that the 60 front only uses 1 ubolt on the right side of the axle , ,, and i think i have replaced the rear axles in them with ones out of 3/4 ton trucks , the single wheel trucks,

[DaHateTank]

LOL...guess my tape measure is wrong

not worth arguing about, IMO.

Spring perch spacing for all 67-72 4WD truck rear axles is 40" center to center.

Spring perch spacing for all 73-87 truck & 73-91 K5/Burb rear axles is 42.5" center to center on 1/2 & 3/4 tons. One tons measure 40.5"

Front axles are a direct bolt in from 67-87(91). You will have to account for the brake line fitting size change.

Front axles up to 1977 or so were exclusively the Dana 44. During 77-80 there was a mix and after 80 it was exclusively the Corporate 10 bolt.

'74 rear axles are NOT a direct bolt in for '70 Blazer nor are '76 axles for a '67.

I had to move the rear spring perches on my '77 14BFF from 42.5" to 40" so that it would bolt up to my '71 Burb.

well i dont know what youre epieriance was , but i have done it over and over without any problems what so ever , so apparently we have had different expierances , you know what youve done and i the same and i have done direct swaps ,

[Mark540]

Just checked for everyone as I happen to have 4 full sets of axles 2 set 67-72 1 set 77, 1 set 91 suburban. Beast388 is indeed correct. fronts on all are the same distance, back on the 67-72 is 40", back on the 77-up is 42.5". Knew this was the case just needed to set the facts straight. mark

[toddol1971]

Hey mac67, it looks like you owe me that plug nickel. I dont know why you would doubt us, & just for the record, i've done ALOT of research on our trucks. The 73 thru 86 1/2 & 3/4 trucks rear axles will not fit. The axles off a 1 ton rear will bolt right up. Maybe thats what you have used in the past. Thanks Beast & Mark. I appreciate the support.. I feel so loved lol.

[MAC67]

im not kidding here guys and im not mad , but i am serious here , , im gonna a few of these trucks if i can find the guys around , but i took a 76 chevy rear 14 bb ff and slung it right under neath a 67 shortbed 4wd , and it bolted right up , maybe someone changed the springs out on the 67 but it was a direct fit , sameway with another 72 pickup we did for my cousin , sameway ith the blazer , ive never had a problem with thewm or had to relocate spring perches , stating my expieriances i have got a 72 blazer right now and a 14 bolt laying in a 74 3/4 ton pickup i am getting ready to swap , i am going to pull it out and put it in , i will let you guys know if i run into any problems
