Hi guys. I found a rear end housing out of a 76 camero. It's a posi with 3.08s in it and it's a 10 bolt 8.5 diff. I have a 8.2 posi in it..but I wanted to put The 8.5 in..since it's set up for leaf Springs.. Do any of you know where I can get link brackets for it. I don't want to hack up the original one. Plus it'...

Hello guys, just trying to work out my ratio for my rear end. With two full turns of the rear wheel, the prop shaft turns 3 and 1 third turns. Does this mean I have a 3.33 ratio? If so, I can find nothing online to suggest that a 12 bolt comes in that ratio? Please help!! Ian UK

My lucky day! I got a nice parcel in the mail today. A friend had a Hurst Competition Plus for a Muncie in a 66 B body bench seat and he didn't want it any more. He is going back to an original shifter in his car, so he sold me his Comp Plus. Now for sure I have to do the Muncie conversion! No pics, we just moved a few...

Hi Does anyone have any recommendations for a proven power steering system conversion for a 1969 Acadian with a big block? I know CPP has a 500 series, is this a good steering box? I am also aware of a pump and reservoir from "Tuff Stuff" That looks pretty nice. I would sure appreciate input.
