Will I need a custom made driveshaft for my SM465 behind my 283?

[Captainfab]

In the case where a trans is used with a bolt on yoke, ie: SM420, SM465, TH400, the slip joint is a part of the driveshaft. That is exactly what I have in my '66 Suburban with a TH400 that uses a bolt on yoke. In fact the driveshaft that I used came from a '70's longbed K series truck with a NP205 and I just had it shortened to fit.

But my question is, a one piece shaft won't work with an SM465, because you have to have a slip joint somewhere in the drive line, to allow for rear suspension travel, correct? And SM465's only accept a bolt-on rear yoke, not a slip yoke, unless I am mistaken.
