need 68 barracuda help

1)Accordind to "Challenger & Barracuda Restoration Guide 1967-1974", "Those with five headliner bows used a perforated headliner, while those with six bows used a corduroy material pattern." They also caution as to numbering the bows as they set with age and should be reinstalled where they came out from as they tend to "set" and the headlinedr won't go back in proper. This is not true if new bows are used.
2)There is suposed to be chrome around the back window.
3) Body color for most, but the formula S model sometimes had a red center section.
4) No idea if it's reproduced or not.
