    I was looking into this when I had intentions of SAS'n my S-10, have the 9" rear, but wanted 6 lug, someone said that was, but want to confirm. Don't want to spend $300 on a set of axles when stock will do.

    if not I am sure someone like Moser or the like would make you a set of axles with the 6 lug pattern. They really don't charge that much more for that stuff. Then you have nice axles too. I think there is probably enough room, but that some of the existing holes may interfere with the drilling. I know you can drill to a GM 5 lug pattern, Dad had a 9" in one of his race cars that just had redrilled stock axles.

    Maybe for the he!! of it I will call an axle company and see what the cheapest route is. Going with the adaptors isn't a bad idea, will also widen the track to sorta match the front. I bought axles for the 9" I had in my Malibu, and they were $300 IIRC. But they were 31 spline Mosers, good stuff but pricey for what I need. I might run the stock pattern, the old man has a nice set of 15x10s that are pratically new, pretty sweet lookin......hmm see what happens....

    There should be plenty of room to re-drill to 6 lug but might need to have a hole plugged before doing so. The cost to have them re-drilled might be about half of a quality pair of axles already with the bolt pattern you want though.

    I had the stock axles resplined before I got Mosers, and only cost me $50 or so, plus studs. Think it was $100 all together. Had the longer racing studs too, so more expensive than stockers....

    Anything from 2.29-ish up to 4.56s guessing factory, but can go to 7.17s I think. I only want 3.50-3.70, maybe 4.10s. Found a set of 3.70 in a yard here, just have to get a set of 3.73 for an HP. But, there are two axles there already with 3.55, one is already 5 lug and leave sprung. One of them there ext cab fronts, other is a 3/4 ton.

    Unless I'm mistaken, ford truck bolt pattern is 5x5.5. That means you could drop a six lug chevy rim on and one lug stud would line up... there may be overlap on a few holes but I think it's do-able.

    Most Ford 9" flanges have an extra large hole to access the retainer nuts. Might get in the way of the new pattern.

    I have 2 friends that had their 9" shafts welded and redrilled for ~$100/pair.

    For some reason I thought you couldn't weld on the flange?? Heating it would take the temper out of it?? I can probly get that done next to nothing.....I'll have to check. Thanks!!!!
