Early SWB Mid Belt and Gear Cover Color

[HKS_TRD]

I'm building up the basic Optima Mid with all NIP parts, and I had heard that the very early Mids had clear belt and gear covers, I have a set of genuine Kyosho SWB Belt and Gear covers, but these are a newer part (you can tell by the header card on them) and not sure if I should use them on this build or not. I have the genuine tinted parts too and don't want to make it look like it has repro bits on it.
I actually have a genuine shell and decal set for it too so I'm resisting temptation to put the vintage alloy wishbones and C-hubs I have on it

I am going to use the Option house wheels (OT-67 IIRC) on it though just to set it apart from the Turbo Mid I have here as well

If anyone can clarify the belt cover situation I can get on with the build
