Get ahold of 71T/A here at Moparts.
He has an ASC&P T/A hood on his Challenger and knows a fair amount about them.
I have an old glass T/A hood on my street/strip 1973 Challenger from Unlimited Fiberglass.
My hood fits very well but does not have the rear screens and squirters, and is not very well finished underneath. It is a bolt on and is light.
According to Unlimited's website they retooled their T/A hoods and the rear screen indentations are now on their new T/A hoods and the underside is better finished.
I bought my hood brand new at a swap meet for $150 many years ago and is perfect for what I want.
There is also another T/A hood advertised on E-bay often that has be getting very good reviews.
