can u keep me posted if u find a bolt in rear I need to find one for my 70 Buick Electra Preferably a 12 bolt it can be a lil shorter
I've been exploring this rabbit hole for almost 2 years now. While I am all for keeping it original, (to an extent) I've been looking into replacing my rear end altogether. However, no shop will build me one. They just want to sell me parts to do myself.
Same deal. Buick used Dynaflows up to 1964 when they changed to open drive lines and more modern transmissions.
what is the primary failure origin for the 9-3/8” rear? Can it handle sustained 500hp/535T loading like in a closed course?
hey can u help i have what i think is a buick axle out of a 74 regal iv been told its a 9 3/8 but no one can confirm has a 2 something gear in it the numbers on the axle are 40628 then a 8 then bl any ideas I'm on larrybowyer5@gmail . com I'm in the UK so can't get any help
More info on the non-interchangeability for 1966 1st type vs 2nd type carriers, thanks to John @66kooch and Jim @monzaz. Mid 1966 saw a running change to upsize the left case/carrier bearing, making 1st type incompatible with 2nd type and later through 1970 9-3/8 Wildcat/Electra/Riviera. If anyone's got a 1st type '66, the only carriers that will fit must be '66 1st type as well. https://www.v8buick.com/index.php?threads/wtb-342-psi-center-section-for-70-wildcat.379034/ Devon
Thanks for the quick reply.. Sort of yes because he specifically listed years of 9-3/8 rear in a previous post. Obviously many of us are on a search. I have a 70 Estate Wagon. Would a 68 Riviera rear be compatible? From everything I’m reading, the answer would be yes… but I just need confirmation. Thanks!
I am currently working with Quick Performance on building me a 9in that will bolt into my 68 electra. They asked for measurements center to center for the upper and lower control arm mounts as well as housing left and right length. I will post up more info as soon as I have it. Should hear back soon.
The complete rear will not work. The 70 Estate Wagon is different. The internal parts carrier, bearings and gears are the same. The axles are different too.
