Selling a 400 to 203 adapter. It comes with the adapter to transmission bolts. One of the mounting holes in the bottom looks messed up (not a problem with a doubler?). I haven't tried to run a tap through it yet. In the pics the adapter has water on it because I pressure washed it. Also I have the rod that goes from the transmission bellhousing to the t-case. Make a reasonable offer on either/both items.
