You only need one major trip where it turns colder than a witches tit, its raining, your wife who isn't crazy about hotrods to begin with is setting beside you cold, soggy, and pissed off---and side curtains start to look pretty good---ugly or not. My advise, and I speak with the voice of experience, is ---if you can afford a hotrod---if you can afford a Bop Top---then pay the $1000, get the right thing, and be done with it. It only takes one screw up while trying to do something on the cheap to either screw up the paint job on the top of your doors, or screw up Sid's Bop top. Then you will pay $1000 for repairs, and another $1000 to buy the right side curtains.---Brian
