The P50's came in several models. Low power in the short housing, high power in the tall. As was mentioned before, the battery voltage was different for the two models. It was only capable of one or two channels max. Under the battery was an adaptor board with the charging polarity protection diode. Peel it up and that's where the PL/DPL board lived. Same board for all models.
EXCEPT... The P50+, a relatively rare P50 variant with a programmable PL/DPL/2-tone board. The program cable for that board was part of the Radius dealer package way back when. In all the years I was a Radius dealer, I never sold a P50+ or used the cable Not a spectacular radio, but I had a few Police departments that insisted on cheap radios and wanted the P50. Surprisingly reliable when new and parts were available.

If so, the 'tall' vs. 'short' was carrier squelch vs. PL/DPL. So yes, that means converting a CSQ radio to PL means changing the case... And no, these are NOT narrowbnad compatible, so they have no value in Part 90. And they were pretty cheap, flimsy radios, hard to work on, easy to break, I wouldn't take one for free...
