windshield seal question

[keg]

I am having the windshield replaced in my 87. I purchased weather stripping for the doors and windows from LMC a couple of months ago, the windshield seal brand is Precision. The guys were out yesterday to install it. They weren't real happy when they saw I had removed the old seal and had a new one to install. They had a lot of problems getting it to fit properly and when installing the black retaining strip the main seal tore on one of the corners. They said the seal I had is very poor quality and not the first time they have had problems with them. They are going to see if they can find a used seal, they feel this is the best option.

After searching here I see others have had some problems with LMC’s windshield seal. I guess if I had to do it over I would have kept the old seal. But as it is I would prefer to use a new seal, is there a new seal out there that will work? Where can I buy one?
