Sorry mate, that's all the info I have with these parts. I'm kinda stonewalled on this end and they're making me nuts.

Hi Everyone, I'm new here and I wonder if you can help me. I need to know the kit/kits for these parts. One is an axle/differential. I think it's from a dragster but don't know for sure. The other is an air scoop (not chrome) and I'm reasonably certain it's from a Revell kit, either 1/12 or 1/16, but again, I don't know for sure. Measurements are approximate. Any help would be *greatly* appreciated. Thanks! CG
