For many years, I've been a short wheel base guy. 1972 CST and then more than a couple Jeeps (don't hate, it was a business thing and since then, I have re-found myself). All that time the theme was to ditch the slip-yolk for a variety of really good reasons.
Now things aren't as much about wheeling. I have a '74 long bed that I'm in the process of installing a 4L80E. About a year ago I searched high and low for a NP241 to mate to it and finally found one. I'm all ready to stuff it in there and my old self is whispering in my new self's ear "get an SYE or you'll be sorry." My new self replies "it's a truck that I have no intention of ever wheeling, driveshaft angle ain't a problem, space isn't an issue...you don't need one.". Old self is stubborn though.
Details for consideration: '74 LWB, 454, 4L80E, 14Bolt, 4" lift w/ rear leafs, 35's, and it's not all about the money BUT money is always a factor (save it here, get something else cool instead maybe).
Does anyone have good reasons why it makes sense to keep the Slip-Yolk over a JB-Conversions SYE?
