A Body A833 4 speed transmission parts wanted

Hello, I am looking to convert my B Body A833 to A Body tail to fit my Duster properly. I am on a budget so I am hoping someone has a collection of parts and can help me out. I am not interested in new Brewers stuff at this time, or overdrive A833 parts. Even a bad A Body trans I will be interested in. My B body trans needs rebuilt anyway so I'll try this. My B Body trans is a 1969 year model 23 spline.

Thank you all for helping me out

Eric..
