55-57 chevy rear

So I had a guy drop off the rear window for a 55-57 chevy truck.. Bad curves on the side.. I heat shrink the middle part of the glass. But i dont even touch the sides since they are curved so bad, the tint barley streaches over the curve..

I need some tips or hints QUICK...
Thanks

do you have a pic of the window?i've done 57 chevy cars.not that hard to do.when you go in with the film,heat the outside of the glass in the corners.it will stick

should i maybe not use to much baby shampoo in the water?

yeh ,that will also help.its a combo of cutting it right,shrinking it right,cleaning it right.it looks harder than it is to do.if were talking about the same glass.

i can take a picture if you want.. it basically looks like a U
