Pictures of your interior needed

I take it you don't have your old one for any kind of reference...
I built my own for like 75 bucks for fives maybe 6 years ago I don't know...
I use the I don't know what you call them clothing hooks on the sides to hold everything up... I would think getting the whole entire thing up there all tight with all the other trim is where you need to be..
Then all the curvatures and everything are taken and to consideration and then you can market accordingly..
