I am actually doing this conversion right now on my '66 Coronet. Call around to your local salvage yards and ask for a tranny out of a 92-94 2WD Ram Truck, early to mid 90's full size Ram Van (150, 250 or 350) or the early 90's Dakota's had them as well. You want the A518/46RH. Most the time you can just reference the 46RH and they can find it from there If you find a 4WD tranny with the transfer case attached you can buy a 2WD tail shaft off the bay for around $65 buxs. You will need to cut the bell off and buy a bolt on Ultra Bell housing from JW Racing, depending on what motor you plan on mating it to. I am putting mine behind a 383 and the part number for that is #3100. There are a couple good "How To" threads here on the site that will walk you through everything from A to Z. Good luck!

Does this $65 tail include the OD unit ? if so that's a DEAL ...

Ive been doin some serious googling and some say the output shaft is too short to just bolt on a new tailshaft. Is this true or was i mislead?
On the OD trans the OD is inside part of the tail housing , you need to have the entire tailhousing with OD inside it ... most parts are the same , the output shaft of the OD unit itself is different ... and you aren't going to be finding it for 65 bucks unless it's junk .

I did this swap in a 71 Challenger. Do yourself a favor - find a RWD transmission. There are so many other problems you are going to have to chase, don't add this to your list. Things that you are already going to have to deal with are:
1) Rework the shift linkage. The OD unit interferred with the mechaical linkage - I went to a cable set-up.
2) Change the driveshaft length. You also need to swap yokes.
3) Rework the transmission mount and crossmember.
4) Rework the bell housing connection - either with a JW ultra bell or a JVX Adapter. I went with the JVX.
5) Lengthen the spedometer cable
6) Maybe modify your transmission tunnel. I had to modify the tunnel frame and some sheet metal to get the engine/trans to sit level.
7) I made new trans cooler lines, went to 3/8". Not positive it was necessary, but I read it was and seemed easy enough. Also added another cooler up front.
8) Add the electrical wiring and the pressure switches for the OD and lock-up controls.
Aside from the RAM trucks look at vans and service vehicles.
Good luck

No adapter needed to bolt to a smallblock..
