We have also used a Bendtsen's adapter who's located in Minnesota. The 400R4 will require a slight trimming of the toe board while the 2004R fits with no trimming. The factory transmission cover will fit over the 400 with just a little tweaking. Picture of a 1952 Suburban that has been fitted with a 700R4 before body was lifted off chassis.
