Will 1970/71 a body side marker lights fit on a 1969 cuda

I tried a search on this to no avail. I am trying to find out if the 1970/71 a-body side fender marker lights will fit in 1969 barracuda side fender marker light locations? 1969's are reflective only while (I believe) 1970/71's are actual light fixture assemblies. Curious if the mounting hole diameter (on the 70/71's) are the same as the 1969. I would love to do this mod if possible. I heard the 1970 b-bodies are a little larger and wont fit. Any thoughts on this, please post. Thanks :)
