    In going to get the front diff out of a 78 3/4 ton and was wondering if the rear springs will bolt right in from the truck on to my 85 blazer.

    1/2 and 3/4 ton are the same distance apart so you should be ok there but i think the length is different, i don't even know how long my 3/4ton rear springs are. /forums/images/icons/blush.gif

    early 3/4 tons springs came 52" or 56" i forget when they changed. Im thinkin it was 75-76ish. After that they were 56" and half ton were 52" so unless they are 52" i am almost positive they wont fit

    I used the springs from a '78 3/4 ton 2wd on my 1/2 ton Sub. They were 56" so I had to move the rear spring hanger bracket back 4".

    The springs from my 77 K20 went right into my 77 K10. (if that helps you any)..... I think it will work fine
