Hey so here’s the deal I’m doing a e4od to Zf5 swap. Had it in mind d ever since I baught the truck but only recently was able to find an idi 4x4 in the junk yard. I have one week to get this job done. No biggie. Can do the swap in a day. Butttt. From my understanding I will have to have my drive shaft lengthened. And that will take 3 to four days for the guy to get around to doing it for me So my plan is to take the shaft off first thing and run it up to him. And then work on the rest of it in the mean time. My question is this. Can I simply take the length of my Zf5 and subtract it from the length of my e4od, and have him ad that much material to my shaft? Sounds logical but don’t know. My truck is a 1990 f250 extended cab long wheel base. Does anyone have an exact measurement of how long the shaft should be for the Zf5. Just to know it is a split shaft with a carrier bearing Kinda goes unsaid but I’ve read that it can very. Any info would be appreciated so I can know what to tell him and get it done as soon as possible. Thanks in advance
