1969 Cutlass S , has a bent axle ( right rear) RockAuto refers to 2 different ones, a ring gear size ; 8.2 and a 8.87 , (or something like that ) so , how do I tell which, without opening up the diff and measureing the gear ??thanks

If you have a Type 12 bolt then neither of those axles. The 1st one you list is for an 8.2" rear end & the other is for the Chevy 12 bolt. On top of that you will have bolt in axles & both of the ones listed above utilize C clip axle retentions.

the cover does have 12 bolts, and thet are bolt in axles, so , where is the best place to get one ?? thanks

I got a couple used ones from Brian Trick (507olds) several years ago. I'd contact either him or monzaz if you want a good quality used one.

FYI, there are different versions of axle shafts for the O-Type rear. The early ones (67-69) use a sealed axle bearing with the oil seal pressed into the end of the housing tube, and the late (70) version uses an open bearing with the oil seal sandwiched on the axle shaft between the bearing and the retainer (same parts as the '71-up 8.5" 10 bolt rear). The axles are not interchangeable, so be sure you get the one that fits your rearend.

I had it out, it has the seal in the tube

Yep, that's the '69 style, original to your car.

so, can I tell Rock Auto, I want an axle with the seal in the tube, bolt in flange, and it'll be the right one ?

You can tell Rock Auto that and they should tell you that they don't have an axle shaft for an O-Type 12 bolt rear.

okay, I got it now. SO, where can I get one, other than OPGI for $200 ?
