1,001 question on tranny swap

[JOJABOY]

I know there has been a thousand questions and threads on doing an overdrive trans swap but here's one too boot. I've looked through the treads but haven't seen a definitive answer.

I'm going from Th400 to 200-4r. I have the trans, lock up, dipstick tube, trans mount, TV cable (still have to get the bracket). My question is in regards to the slip yoke.

I know that the 200-4r has the same mount position as the Th400 and is 11/16" shorter in overall length. My question is will that 11/16" make a difference? Does the slip yoke need to be all the way in? Or will I need to get a longer yoke and trim it down?

Also....Am I better off getting a 27 spline 1330 series slip yoke vice getting the 1310 to 1330 conversion U-Joint?
