Wheel swap considerations

Hey Team LaLD. I have a conundrum. My ebay finger got a little twitchy and I ended up picking up a few older models to add to my porsche/amphicar collection. I am now trying to decide if I should swap some RRs onto them. In particular I think the 935 and 914 would look so much better. Thoughts? On a side note don’t the decals speak to the HW era they were designed in?

Also still looking for the Mopar Power wagon and Forza 2002 if any one has an extra for trade.

Thanks for the help!
