I'm swapping a 4500 into my 85 4wd longbed.
I would NOT measure for a driveshaft until everything was bolted in. Too many variables that can screw up your measurements. Driveshaft work isn't cheap, especially when you screw up.
The 4500 is much shorter than an auto (your 700 and my 400). I am not able to use a 1-piece shaft because I need one right at 64 inches. A one piece shaft that long will cost you dearly! Therefore, you may need a two piece shaft (and x-member and carrier bearing). It's a snowball effect. Once everything is in place you need to account for and adjust pinion angles accordingly or expect vibration.

Embrace the fixed yoke. A slip yoke is a waste of money and a step backwards.
