W108 Side markers/reflectors

[n10]

So I am having a hard time finding replacement reflectors for the sides of my car.

The current ones on the car have two small bolts going through to the inside of the fender secured by little nuts. The bolt ends on the reflector side are actually "T" shaped and hide under the chrome trim of the reflector.
All the replacements I have found are completely different in terms of mounting. They have a clip on one end that holds the reflector to the rubber surround inside and an external screw that goes through the chrome trim and into the fender.

From what I am seeing these replacements will not fit/work with what I have originally. Does anyone know what the deal is with these?

I hope this all made sense
