If you do replace the crush sleeve be aware that they sometimes take a disturbing amount of torque to begin crushing. Once they begin moving it gets much easier to do. The last one I did was ugly. Pneumatics wouldn't touch it. I'm sure you could have done it with an industrial 3/4" drive but I don't have one. The torque required was bending my steel table. I had to put a jack under the table mounted vise, clamp the yoke in the vise, put a 4' long black pipe over the ratchet handle, and test the lifetime warranty on the tools. I had been pulling hard on the pipe with no results. Then, I cleared the floor behind me (landing zone if something broke and I went flying) and laid into it HARD. It went but wasn't happy about it. https://www.youtube.com/watch?v=8T8ZG5DKsi0

Well maybe, but it is what it is, and I agree about getting the sleeve to begin its crush can be a task. I used a 4 foot cheater and a MAJOR vise at work to get the job done. Would never do it again, solid spacer only if dealing with a 489.

Boy does that ratchet make all the difference...

I missed the obvious that with the 727 being longer you will have to have the shaft shortened/balanced. I'd get the front yoke (& a conversion ujoint if the yoke you locate is a 7290), correctly measure the C to C dimention to give to them (rear loaded/car reasonably level) then shaft butted & subtract 3/4". spicer precision neapco are reportedly good ujoint brands with spicer being my #1 choice. there's no downside to the conversion joint. Ma's super stocks ran fast in the quarter in the 60's with 7260's/no issues & it being half an half ain't a problem

Why does everything always have to be the hard way??? If you took out a 904 that means its a small block...in stock form their not notorious for being torque monsters. Get the 727 yoke for the small u joint...set it 7/8th's of an inch from bottoming out in the trans...measure and order a new shaft with small joints on both ends. Any 8 3/4" pig is kind of like a sleeping dog...don't F with it...especially when your not sure what your doing.
...FAFO...
