A833 overdrive V8 bellhousing?

Im new here and to mopars. Did you find a bellhousing and did it all work out? I swear i viewed this post before and there were two replies of members claiming they had this bellhousing with the 5.125 index, but now I do not see those replies.
I have a 76 duster with a 225 I just picked up and a small block waiting for me to acquire all the parts!
