    Marty, I used a 5.57 ratio R&P in an old split housing Ford 3/4 ton rear axle. I took it out of a heavy duty Stude step van, fit perfectly. Greg

    Thanks. I'll pm you tomorrow regarding these setups. If you have a setup like that I will be very interested in learning more about it for a future project.

    @alfin32,
    That rear cover is kinda special. When Halibrand moved from Culver City to Torrance, some covers were cast with the "Torrance City" markings. Later versions were changed to "Torrance", which is correct as Torrance was not a city at that time. Don't know if it ever was.

    Was it a quickchange ? I don't think you can cut 10 splines, into an original pinion shaft, that was setup for a yolk. The only commercial quickchange ratios I have seen, are 4.11 and 4.86, with the exception of Winters Xtremeliner, that is available with higher ratios for Land Speed use. My Brother's OT T-Bird has one with 3.00 R&P. IMG_0627.JPG

    Marty, The 3/4 rear end was not a quick change, nor did I make it into a QC. It was simply a split hsg Ford with an open drive shaft. The Stude hsg was basicly identical. The 5.57 ratio was ideal for my 57 Ford, 406 engine, running on a 1/2 mile dirt oval. Greg

    Greg, that was the Timken axle, used by Ford and Studebaker. I bet that '57 was quite a ride with a 406 ! 15 years ago, we ran a '39 Merc coupe with a 351, on a 'small quarter mile dirt, and ran a 7.33 gear.

    G'day
    I have a 301 Halibrand that needs a lot of work - welding repairs etc however I would like to save it if possible - it has 12 studs for the Side Bells and needs all the internals . I also has the in/out lever assembly for the input shaft however some parts are missing so I intend to change over to a solid input shaft. If I understand correctly the Winters Champ QC is shorter than the 301 so I am wondering if the Winters 10" 4.11 ratio Ring and pinion will fit the 301. I have done a lot of searches and can't seem to find a definitive answer so can anybody help me with this?
    Also I would like to use a DPI Differential but am unsure of which one to use for the street. There is a "DPI / Winters Quick Change, Black Gold Track Differential,10 Inch/ 12 Bolt" on ebay just now- can anyone tell me if this is the one that is suitable? I realise that there is probably some modifications to be made to the DPI but I think I can get those mods to happen out here in Aussie - just need to know that this is the correct unit to buy. Will the Winters Ring fit the DPI mentioned above?
    I intend to machine some adaptor side plates from the centre to the Flathead trumpets but this is probably a subject for another day once I get all the parts sorted out.
    Thanks in advance for any help you guys can give me.
    Regards Karl

    I answered Karl privately, but for anyone else that is contemplating something like this.
    Welding a broken case correctly is a $500 job.
    The Winters V8 units are shorter tan the Halibrand V8 (201) but the Winters Sprint and Halibrand Champ are virtually the same length.
    The Ring & Pinions are interchangeable between brands, but to use the late model Timken foller bearings in a case made for ball bearings requires some rework on the bearing race.
    Using the tapered roller bearings on a ball bearing pinion requires the same work on the race and some expensive bearing cones which also need massaging.

    The TruTrac style differential (which includes the DPI Gold Track) can be used in a Halibrand case or any of the narrower Winters, Frankland etc. Modifications will have to be made, particularly if you want to run the adapter side plates to utilize the Ford V8 axle trumpets.

    This is the expensive way to build a QC! That can be mitigated somewhat by buying good used parts.

    @42desertrat,
    I've done that install before. You can leave the 5 on 5 hubs and use either disc or drum brakes. Narrow it by pulling the axle tubes and reinstall after cutting to length. Shorter axles will be required.
    Or, put late model Ford bearing cups on the tubes and use drum brakes or discs. Aftermarket axles.

    I can give you more details, if you need them.

    I don't know how I missed this thread. I currently have 2 deuces with Winters V8 rears and a third on the way. I'm amazed how many Winters rears I sell each year. Never had any problems with them to date.

    It is going in a 38 gmc replacing the s10 rear end. I think the width should be okay. Disk brakes would be good. I was looking at the clamp on metric caliper brackets from the circle track world. The 5/8 lug bolts look to be a bother for running street wheels.

    There are 1/2" lugs that have a big knurl on them. I have never been able to redrill those damn Grand National Hubs. Be sure the centers of your intended wheels will fit over the hubs.
    I would use the weld on brackets. You can get them for both the metric and big GM calipers.
