Bill from what I see there everything could be used with the single biggest improvement being the side engine cowlings. The support frame will need the detail removed from the plastic, but I suspect that is also a requirement of the intended model as well. in the belief that the other model is good scale wise I do not expect you to hit an issue with the set. The pennant holder is quite nice. I don't know if it does $46 worth of improvements.
Thank you, Darren,
This Lion Roar set is the one the Pit Road is based on and sells for 1/4 the price.
