Hi Guys: I have to change my 1 ton 727 from a fixed yoke to a regular tailshaft and yoke on the driveshaft. I believe that all I need to do this will be supplied by a junker transmission. I don't think it matters if it is BB or SB but maybe the clutch housings are smaller on the SB ones. Has anyone done this and can give some advice. I may be dreaming but I don't think so. Its been 25 yrs since my last 727 rebuild. Thanks

I was told by a transmission rebuilder that the guts from a big block trans will fit a small block and vise versa. I would think that all it would take would be a tail shaft and its housing although I am no trans guru so maybe someone will step in with alittle more knowledge and give a definate answer.

Only difference is the bellhousing. Why exactly do you have to change? The bolt-on yoke is stronger.

I want to use a regular slip joint driveshaft.The fixed 1 had a steady bearing and I only have a shortbox. Any old short box automatic tranny driveshaft from the junkyard will work and I think even the 833 4 speed one.It has an 8 1/4 rear so no need for a hugh ujoint or shaft. I think something else will twist off first.Time will tell. Thanks for the feedback.

Oh, you're putting a 1-ton trans into a 1/2-ton shortbed. I thought you were converting a 1-ton truck to slip-yoke lol. Makes sense now
