I bought 50 feet of E145 last year. Fits all the doors on my 1978 B. Almost exactly the same shape and structure as OEM, although in my opinion it is a little on the floppy/soft side. But for less than a hundred bucks, and the impossibility of finding sedan and wagon weather strip, I'll take it. The only real problem is you have to punch the clip holes yourself and that's a time consuming job. Money or time, money or time

I think they'll send you a foot sample if you want, or even if you have to pay for it you're talking less than 10 bucks
