720 door seal questions

[Telkwa]

Good day to everyone -

I'm googling around for 720 door seals.  Some websites specify left or right.  JC Whitney's Fairchild door seals have no indication of left or right.  VintageRubber.com states that they sell a 13' long piece that the customer cuts and glues together.

 

Here's an example.  I wasted 10 minutes going back & forth with a Live Chat person at Car Parts who never did answer my question about left or right but assured me that the product was of the highest quality and that it would fit.   

 

Prices range from JCW's $6 to $50 and beyond.  I'm looking for a little help in finding a good product (for both doors!) at a reasonable price. 

 

Several forum members have mentioned datsunlandsocal but he doesn't list any 720 parts.

 

I can find wrecking yard door seals but our truck is an '86 so they're all going to be as old or older.
