Need a professional weatherstripping installer

[bigdon-70blazer]

I need a professional to install the top weatherstripping on the 1970 blazer. It leaks and makes me angry. I totally installed the new stuff when I completely rebuilt everything but the weatherstripping I read and installed it just like it was on it before but I still have pesky leaks. So upset I can't fix this on my own. Maybe a professional knows the right tricks that I don't. Needs to be near or in Missouri. Are there any of you with same issues? I am going to tear it down this winter and get it dry. Please help me my Missouri brothers...
