    Pontiac/Olds. But maybe not, what's the wheel bolt pattern. P/O is 5X5.

    World famous (our "world" anyway) 57-64 Olds/Pont. Appears to be the Olds style backing plates/brakes (they're all interchangeable). Lots of info on these right here on the HAMB, including several specific threads. Butch/56sedandelivery.

    Pretty neat - those big Olds/Poncho axles used to be what everyone ran when they wanted to make sure their rearend wouldn't break. I think you can still get quite a bit of parts for those axles - gears and diffs, etc. I woulda liked to have had one before I started building my roadster, I woulda used that instead of the 9" Ford.

    To me it would be a shame to replace an Olds rear with a 9" Ford. They were the first bullet proof rears that all the serious race cars ran in the 60s. Yes you can still get parts for them. An Olds rear is a hotrodding icon. IMHO You will find more vintage Halibrands with 5" bolt patterns than the 4.5 Ford pattern. Probably not a popular opinion but If you grew up with the legendary Olds rear you might understand my feelings. Most probably won't.:(
    Sorta like putting a MII front suspension in to replace an old dropped axle.

    If you keep the Olds be prepared to spend big bucks. A 9" is way cheaper to build.
     
  11. No it wouldn't especially when you consider how close to branson I live. ;)

    9" axles were around at the same time. No shame in switching. Just as traditional.
     
  13. Tommy,it's not nearly that bad!,a 9" Ford is except-able,,the Mustang II is a down right sacrilege ! :D HRP

  14. Not hardly. Back then the O/P rear was king shit and unless hes replacing it with an early housing 9" its not even close.
     
  15. Ford 9" rear axles were introduced in 1957,,I believe the Olds introduced their HD rear axle in 1957 also.

    I the early says the Olds rear axle was the favorite with drag racers and hot rodders.HRP

    Actually the "good" Olds/Pontiac rear end was introduced in 1957. I think the reason they were THE rearend to run back then was that they were stouter than the Fords. They were still in cars making passes while the Ford guys were picking their pinions and driveshafts up off the ground. I don't think Ford rearends were the hot setup until they started beefing them up a few years later.

    For me it's a nostalgia thing. I only blew one rear end...a 55-64 Chevy...blew the spiders and then welded them up.:D Hell I can't even blow an old Ford banjo:D WE have some guys around here that can build a nice Olds rear. I wouldn't rush out to find an Olds rear but if it is already in the car ...it sounds like a waste of money IMHO
     
  19. You guys must have missed the word HOUSINGS :rolleyes:

    I am not saying the 9" was as popular or as good as a rear end... but there are alot worse options he could be replacing it with.
     
  21. First pic=traditional.
    Second pic=stronger, but not traditional.

    Not all 9" rears are created equal.

    So, I'm wondering, if the 57-64 olds/american pontiac rears are strong[canadian pontiacs use a chev rear] What about 56 olds, are they any good? My son has a 55 buick and needs to change to an open driveshaft and I have this 56 olds rear laying around that is the right width and has a 5on5 pattern.
     
  23. No, they used really coarse splined axles. For a stocker type car it will be ok, but if putting down power with wide or sticky tires, the axles IMO are the weak link.

    wasn't till the daytona carrier was built that the 9" was just as good , seen many a O/P behind fuel motors that would gernade a non Daytona carrier .

    freind of mine has one that came out of a 60's nitro funny car , many years abuse on it . all we did was rebearing it and weld ladder mounts to it , it will live a leasurly life behind a Blown and injected BBC in a 62 II ..

    Originally the popularity of the Olds/ Pontiac rear ends was due to the fact that a 40's olds pumpkin was a bolt in on a 57- 64 housing. This left you with a strong housing, bullet proof axles and good brakes. The 40's olds rears were almost all 4.38 or so ratios. Instant drag race parts at junkyard prices. Or so my failing memory says. That's my story and I'm sticking to it till corrected.

    Seems to me that the hot tip was the Olds station wagon housings. I watched a guy put one in a Pro Stock Camaro in the early 70's. That could be why your backing plates look a little strange.
