The 70 rear is 5/8" wider per side than the 66/7. I found a 66 rear for my 70 and it sucked the tires right up in the wheelwell, go the other way and tires are in the fenders.

would the axle in my 67 lemans be considered a 8.2" gm axle? the tag on it is long gone

If the diff cover is the same as the one pictured it is a BOP 8.2"

was that the only option in 67 with a 326? could i tell by the vin or anything?

no need for tags. just look at the shape of the cover. particularly the "dips" on each side.

where can i get a lower ring and pinion ratio? all i can find is 3:55 and higher I just want to rebuild my stock unit but the gears are worn out causing a bang. not sure if i should but a used axle or rebuild mine?? cost plays a big factor here. i am using this to just cruze nothing crazy

If you can find a highway gear single spin rear for a 66, it shouldn't cost but a couple hundred bucks, just a take out item. To replace the bearings in yours, I don't know, $500? Maybe less, may not be the gears. To rebuild your rear, new gears and Posi is about $1500. You can convert to a 66/7 Chevelle 12 bolt with a conversion U-joint, gain all the plusses of a 12 bolt, but keep the narrow-ness? of the early rear, that is bang for the buck your best bet.

Randy's ring and pinion will sell you a posi carrier for any gear ratio you want. I ordered an Auburn unit, 3:55 gear set and an installation kit, works great.

I'm pulling the rear end off my 66 which is a 2.56 ratio right now and replacing it. Its not originally off a GTO but fit perfect, no tire rub. I will be selling it so if your interested let me know, shipping would be the only pain.
