I have an 83 GMC I bought off a friend a few months ago. When he bought the truck in '91, it was a 3-speed. He converted in to SM465 in 92, and based off the list of parts he bought for the conversion, reused the 3-speed cross member.
Been under the truck several times and looked at that cross member and it looks like it could possibly work with an auto trans as well...
