    hey after work today i went to the junk yard near my house. and saw the truck thats been sitting there for a while. the junk yard guy is my friend he say he was suprised to see how nice that 1975 chevy truck rides and runs. so i went to look at it.. its rottened out like hell! so i looked at the axles.. ooo its a 3/4 ton. 14 bolt rear.. front i would say d44. but i didnt want to buy it til i get ur options. it has a 410 gears, looks fairly good.. guy wants 500 for whole truck.. i dont want the engine, tranny. so ill try to offer him 300 for it.. what do u think? 1975 too old? 89 thousand miles. just dont want to be suckered.. thanks

    should be a d44, never know though, but stock that is what it would have came with. axles are prolly fine. worst case they would need all new seals, bearing & brakes, but if it is a running driving truck u should be able to tell what they need.

    around here that pair of axles goes for $400-500. don;t know about your area.

    im aware of the seals, brakes, etc.. just wondering about the axles cause someone say newer axles is better so im curious about that. my truck is a half ton now, and will be used at weekend driver, crusin at nights etc. plus offroading too aswell.. not too extreme like rock crawling.. trail yes, tight trails yes, mudding yes. rock crawling some. not major.. thanks for ur reply.. anyone else? would like to have a debate about that. anyones input is good. need to know pro and cons about them too.. will go back tomorrow to take pics and post them.. will try and get numbers off of the axles too.. thanks!;)

    old axles just have more wear in them. imo the d44f is stronger than a 10 bolt, all be it not by much. what do u mean by old axles are weaker? what are u comparing.

    I would do it also, you should have everything you need by buying the complete truck to swap them in.

    I'll take the 203! And those axels should have flat top knuckels on them, so thats a plus. And 4.10 is good for what you want to do.

    I just saw the pics of your truck, your really moving along! Must be a PA thing.:D

    hmm I just meant the axle parts to do the swap, but if you can get them to throw in the engine and trans I'd do it. Cept I don't think the 400 from that combo will bolt up to your 205.

    well i wasnt feeling good this morning, (told my boss that:D ) anyhow i called off.. i deserve it! havent gotten any days off in 6 or so months! and what sucks! is i work 98 miles away.. thats 1 way! driving my 03 silverado.. man that truck is great on gas! i get mostly 22 mpg. and i have a pukin 2001 saturn L200, with 4 cylinder and average is 28mpg:( so i rather drive the truck.. bigger tank.. less fill ups, and runs better since saturn wont go up the hill too good.. needs work.. never got around to it! and average is 4k miles a month. thats abt 24k miles already in 6 months.. dohhh.. too many miles on my truck and my car in very little time! am thinkin abt quittin the job soon and get odd job til i find a new permat. job. anyhow, enough of my bsing.. off to the junkyard to snap some pics of the truck!:laugh: will post pic soon of the axles and truck.

    1975 3/4 ton axles were under my 83 for a few years. the front was a dana 44 with flat top knuckles. I eventually parted it out when I went to a 60 and got more out of it then I had invested even with the rebuild.

    Buy the whole truck. use the 203 for a doubler. swap the axles into your truck. sell the engine and trans. scrap the rest. steel is still paying well.

    if you got the axles for $300 and the front is a flattop you can part out the 44 and have a free 14 bolt and some money for your time.

    sell it like this.
    8 lug hubs and spindles. no less then $120 I have gotten more
    flattop knuckles. $100+
    gears $50+
    carrier $30+
    shafts $20+
    yoke $10+ if its a u-bolt type, strap type throw it in the scrap pile
    cover $10+ if its the stock HD piece somone will buy it for a trail spare

    all those numbers are lowest actual amounts I have gotten for parts on Ebay. I have the ability to tap the knuckle so I get a more for them. most of the stuff ends up going to california.

    They might have been referring to D60's, because the older ones had neck-down inner shafts. Other than that, I think D44's stayed pretty much the same :confused:
