Chrysler trim rings originally used on the 1970 and 1971 15" x 7" Rallye Class I wheels, wheel part number 2944390, will fit the 15" x 7" police wheels, wheel part number 3766077. The 1970 15" x 7" Rallye Class I wheel trim ring with chrome, or polished, finish is part number 3461043. The 1971, and some late 1970, 15" x 7" Rallye Class I wheel trim ring with brushed finish is part number 3461222. These trim rings are 4 inches deep. Trim ring 3461043 was also used on the Challenger T/A as the standard 15" x 7" black painted wheels, wheel part number 2944450.
The 3461043 and 3461222 trim rings fit the police wheels properly, but the inner lip covers the outer edge of the slots. The inner lip of the ring fits the Rallye wheel or a solid 15" x 7" painted wheel better.

The Magnum GT wheel is dimensionally the same as the police wheel, albeit not as heavy duty, but lacks the center hub cap nubs. Looking down at the wheel, at an angle, the slots show up better.
NOTE: The original Magnum GT 15" x 7" wheel and Super Coupe 15" x 8" trim ring, part number 388094, is a similar polished trim ring, but has a more slotted valve stem hole.

Both early numbers for the 15" x 7" wheels were reissued, with a "P" prefix as P3461043 (polished) and P3461222 (brushed) under the Mopar Performance "Restoration" parts, with new tooling, which fits the 7" wheels. These Mopar Performance trim rings were discontinued in the early 2000s, but then released again under P5153310 (polished) and P5153311 (brushed). These are now discontinued too.
The 2.5 inch deep trim rings also fit the police wheels, but leave a gap at the center, and also cover the outer edge of the slots. The first version 15" x 6.5" Rallye Class I wheel, part number 3699066 was released for the 1976 model year. The trim rings used for that wheel were made on the 1970/1971 tooling that had been modified for the narrower ring. The 1976-1977 15" x 6.5" Class I production trim ring was part number 3699100, which was polished. 2.5 inch deep trim rings were also released under the 3461043 when Chrysler re-used the part number in a confusing series of re-release and re-use for 2.5 inch and 3 inch trim rings.

I have not used any reproduction trim rings, but Wheel Vlntiques makes a reproduction of the Chrysler 3 inch trim ring in both polished, part number 3003-P-1, and brushed, part number 3003-B-1. Summit and Speedway Motors list the trim rings.
I also have not used general aftermarket or other car company trim rings, with the exception of some GM trim rings from a Cutlass that I tried in the late 1970s on Rallye wheels. The ring looked okay, but not right, and they did not fit well with an inferior clip attachment.
With all that said, I don't run the trim rings on police wheels, just plain like this:
