I just recently picked up my dream shorty. It's the first van I've owned in years. Loving it so far but it still needs a little tlc here and there. For instance, The seals around all the windows need to be replaced. It's letting air and water in when it rains. Just driver/passenger and 2 rear windows. No side windows on this van. Anyone selling these and otherwise what's the best replacement to buy and method for replacing these? It's a 1981 Chevy G-10.
