lynn..theres always more...everyone thinks the olds 12 bolt is a chevelle 12 bolt...you'll find the right one..

i have one with 5.13s or something like that, if your really needing to pull something....like the wheels...just kidding...but i do have one with 5.13s too bad they cut the center section ears off it....

I am not really looking that hard. I won't be abusing the current 3.36 10 bolt. Installing a 4L60E tranny right now. New engine is very conservative, so shouldn't be a big deal. When I do local searches on CL, there are a few "standard" I always plug in just to see if there is a deal. "12 bolt" is one of them.

Lynn. another good option would be 71-72 cutlass, skylark 10 bolts - they were 8.5", use bolt in axles (that are not tapered) gears and posi's are alot easier to find than 12 bolts
I wouldnt hesitate a bit using this rear. I have built many in the past let me know if this interests you I know where a couple are
Oh and avoid the Olds 12 bolt - hard to find parts for

Thanks. I will keep an eye out, but like I said, I am in no hurry to replace this 10 bolt. I just won't abuse it.
