I used rubber parts from LMC when rebuilding the vent windows on my '53. Four months later the rubber was shot! It's cracked and split all the way around both windows. The rubber looks 50 years old. I am P.O.ed
I've already ordered Steele rubber to replace the LMC rubber around my windshield and will be replaceing the vent window rubber with Steele. You get what you pay for.
