Which way to go? Opinions...

Budget is tight. Don't plan on finishing it overnight just want to get a good base. Getting a killer tax return so I thought I would get at least one big dollar item. (Anything over 500 is a big dollar item to me) thought the Ez's seemed like a pretty good deal. Hope they are still available next week when I should have the money. Trans was already slipping last I drove it. 741 case, small bolt pattern. Need to upgrade that I know. I did have a disc set up off a 74 duster but i sold it. Do want big bolt all around.
