Been there. The one you need is about 1/8-3/16” larger in diameter.

2.45” Apparently they just started making them.
I was able to find new old stock at the supply house.
The packaging was old and yellowed. The counter guy even commented. “ I wonder how many times these have been inventoried”
That size has been around for a long time. Just not commonly used.

Just an fyi, I was able to punch a regular range rs cover with a two inch conduit size cutter, then over cut slightly with the same cutter, and it fit snug.

Thought to add a few more pics to this thread, since I am helping a friend install a new Leviton "EV" 14-50R, and have both a new and old one to photograph.
This thread has mentioned the new Leviton "WR" (water resistant) version, but wanted to say there is also an updated 14-50R-B0 (that's B-zero). I picked one up at a big box store for $39. So not crazy expensive, and miles away from the prices a few years back being charged for the Hubbell. And it has the little EV outline on the face! If you are locating the receptacle inside, this might save you a little over the WR version.
I agree with everything pointed out earlier with regards to the difference between this new 14-50R-B0 and Leviton's old standard #279 receptacle. The new one is deeper, heavier, has revised clamping for wires (with Allen screws), is marked for copper wire only, and the torque spec is 75 in-lbs, a big change from the old 25 in-lb on the old model. The new design is very similar to the Hubbell.
And they make a point of stressing that new torque requirement. To hold 75 in-lbs for at least 5 seconds, then torque them all a second time. So you have to suspect Leviton is worried that at least some of the problems seen in the field are from improperly tightened connections.
And as Retirede pointed out, I do NOT see any temp rating for wire terminations anywhere. Not on the device nor the instructions on the inside of the box. So presumably limited to 60C.
Lastly, as pointed out, the cover plate is bigger. I am using a 4&11 square box, and the RACO part# is 888 for that raised surface mount cover. My supply house does not stock this part, but had one next day from the warehouse. Again, as Retirede mentioned, not commonly used.

To clarify the Original post asked about an L14-50 configuration which does not exist.
14-50 is a strait blade 50 amp 4 wire.
L is the reserved nomenclature for locking devices and there is not an L14-50.

50 amp "range receptacles" have been de-engineered over time by marketing to become as small as possible (maximize manufacturers margins) and to carry the load of a typical range.
I am curious if anyone has ever turned on ALL devices on a typical range (oven and all burners) to high and measured the current? Typically maybe only the oven and one or two burners, even Thanksgiving maybe all on for four hours or so.
Then consider an EV charger, full 40 amps for 10-12 hours or more? Definitely requires an heavy duty receptacle and copper wire in my estimation.

Sure with all the eyes and oven going it could overload but in most cases the oven is heated up and then goes on and off so the load is not a continuous load. Even at xmas and t-giving you usually don't cook with all the eyes on high.

Any 50 amp listed receptacle should be able to carry 40 amp indefinitely. If it cannot then there is a problem with the listing of the receptacle.

Using a receptacle for a charger requires a GFCI breaker in here in NJ. So...we always convince customers to hard wire their chargers.
