opinion on aftermarket weatherstrip dealers

[71lwb]

hey fellow truck owners, i am restoring my 71 lwb c/10, and am looking to buy a complete weatherstip set including vent window seals and window felts. i have been purchasing aftermarket parts from both southern kentucky and brother's , and have been happy with the quality of both of their product lines. i know that weatherstripping is very critical when it comes to a proper seal. my question is, have any of you purchased from either of these companies, when it comes to the weatherstrip kits, and how satisfied were you with, the quality of the weatherstipping, fit, and seal. there seems to be a large price difference between the same kits from one company to the other. southern kentucky has a kit for 179.00 , but the brothers kit that includes the vent window seals is 264.99. ( it also includes all of the misc. rubber bumpers)
southern kentucky has a kit with all of the rubber bumpers for 219.00, but all of the little rubber bumpers aren't a nessecity for me.
in advance, thank you all for your opinions
