Swap 904 to 727?

You also can not use the center link from the 69 K frame, that has to come from a 66 and earlier car, and needs to be from V8 car, unless your slant car already has one in place! More common to see a V8 centerlink in a 66 slant car than any other!
The center link on my 66 /6 has about a 2" offset on both ends. Is that typical of a /6 or v8 center link?
