He did cletis. In the welcome center where you and I replied he said a 51 pickup.....a link also provides picture.
You may also want to consider the 7" booster/MC set up from PirateJack.net (Asheville,N.C.) I think it will work either way and its also not as "costly" as other vendors. I tried them and like it. Comes with all the brackets ect. You may just want to make sure it'll not interfere with the rear cross member as well as the tranny. Nice folks to deal with.
Good luck.
