I made up one that mounts to the k frame bolts, Just 1/4 X 2 flat stock bent to fit with an I beam and two casters welded to it. You can buy similar ones.

NOT SURE WHY THIS POSTED WHILE I WAS STILL TYPING.............

A word about 727 mods. It's very popular to add a "shift kit" to stiffen up the shifts. However, the shift point calibration, which is custom to each trans based on the engine power, rear end gearing, and car weight, goes right out the window. A good transmission man can recalibrate it, but its very time consuming, and hence expensive. So the trans may upshift too early or too late, and may not downshift when you think it should. If you do this, make sure to tell the trans guy to keep the original valve body and all related parts for you. It can then be returned to original.

NOT SURE WHY THIS POSTED WHILE I WAS STILL TYPING.............DUH

I'd suggest you subscribe to Mopar Muscle and / or Mopar Action magazines. Lots of purveyors of suspension systems and many other goodies for new and classic Mopars. Some good "how to" articles from time to time as well.

For my 2 cents, if I were going to drop a late model Hemi into a '73, and wanted an automatic, I would not mate it up to a 727 unless I had no other choice. I'd go for the new trans that was with the engine. Much better performance with 5 or 6 gears. Alternately, an earlier A518 (non-electronic ), or a Kiesler, which are both 4 speed with fairly tall overdrives. Of course these choices require some mods for the shifter and tunnel clearance. Don't get me wrong, the 727 was a great trans for it's day, and about as bulletproof as it could be. It's just nice to have more gears for performance and economy.

I dont have a transmission anyway so I would go with the trans that mates with that engine.

Now that you're at that point, what's next? Sandblasting? So far so good
