    I am putting a 383 MOPAR into a 1948 Dodge pickup. I have a 727 trans out of a motor home that has the emergency brake on the output shaft. Does anyone know if I can remove the emergency brake and use a standard driveshaft or am I pissing into the wind. Thanks for any help.

    As far as I know, that is a bolt on unit and you may need to find another tail stock and related internals to make it work.
    No problem with the tranny itself.
    Could you post a picture of your set up? Might be a good way of dealing with a problem I have with mine.

    Don't have a pic but the end of the tail shaft is threaded for the E brake drum nut. I was wondering if that could be cut off and use a standard yoke?
     
  4. does it look like this?

    If you are talking about using a standard passenger car slip in style yoke it will not work. You have to change the extension housing and output shaft which requires disassembly of the entire trans. If you want to use a bolt on yoke as used on devorced transfer case dodge trucks that will work as long as you have the correct spline yoke.

    Remove it and count the splines. Gat back to me as I have a couple of the yokes and might be able to help you out.

    Just did one for my car you need a donor car style tailshaft housing along with the center shaft,trans has to come apart...at least you get to check the internals to see if trans is any good......good luck

    Why not just unbolt the unit, re attach the drive shaft to the fixed yoke and put a slip yoke in the driveshaft? you are going to have to get one made anyways... Easier than swapping tail shafts etc...
     
  10. The tail shaft goes right to the flange on the back - the case for the tailshaft bolts on, but the shaft is quite different.

    The driveshaft bolts on with a flange right? that brake drum can be removed and the driveshaft flange will bolt onto the flange that is remaining after removing the brake drum... thats how it was on the early 3 and 4spd trucks and I dont think they changed the design on the later 727 w that brake option ...
     
  12. So then you have this heavy ugly tail shaft and have to build a slip joint into the drive shaft or use a Ball and Trunion joint to bolt to the flange. Much better to find a 727 donor and pirate the tail housing and shaft from it I think.

    The op never mentioned if his trans looked like the previous photo so some guessing is still being done.
    Perhaps he has the more common trans like this one: (sorry for the size of the pic, I 'borrowed' it from the web)

    This trans can be used w/o the brake as stubbs offers. Plenty of driveshafts are made with the flanged slip yoke bolted to the output shaft and the 'slip' into the tube...common on 2-piece shafts.

    In general terms, there is no shortage of 727 trans. If the op needs a short tailshaft then a trans out of a van or class C MH is the way to go. IMHO, there are just enough changes between make-model-years that swapping tails should be done by someone with plenty of inventory to pick parts from.

    727s are all over the place. I had a cracked valve body on the 68 that's bolted to the 383 in my Stude and for $125 I found a complete low mileage 72 transmission. Over 1300 miles later and still no problems. I still have the other trans and it can be a donor for $75, it just couldn't go into 3rd.

    That pic is exactly what I have. I can use a long or short tailshaft. I think I will continue looking for a car trans. This one will work for mock up to get the engine in its proper place. Thanks for all the help.

    Why take the E brake off ?- the 1948 P/up had the e brake in the same spot on the manual gearbox so this would offer a direct replacement location as what it came out with

    Unless you have another working e-brake leave it there.
