68 SS Door glass or lexan ? your idea ?

I am finishing my Tribute to the 68 Hurst Hemi Cuda. Since the thinner door glass is no longer available, do you think I should leave the stock glass in place and add the straps, or buy Lexan ?
Bickell sells the exact reprop of lexan 3/16" for $ 460.00 a pair, but if everybody thinks that's what I should do then i will.
Building as close to original as possible, when delivered in 68.
thanks
