Not to be a smart. What are you trying to set up? That's a clutch style as stated. You can find new carrier assys for about the same money. Below is a link to and eaton Tru trac. It doesn't have clutches but worm gears that actuate it. May want to give Cas there a call. If your trying to do things economically I understand. Just trying to help you out.

Also I ran into the same situation with prices. I ended up going to a Strange S-60 for about the same money I would have had in setting up the 8 3/4 housing the way I wanted. If I had gone with a clutch style carrier in the S-60 it actually would have been cheaper than the 83/4.
