Weather seal question

Any ideas on where the best place is to buy complete weather seal kits? The only place I've found that has the majority of what i need bundled is justmopar.com. I've got a 71 Demon and will be replacing all the seals, weather stripping, bumpers, etc. They want $595 for the "deluxe" kit and $119 for the door sweeps or whiskers.

Any input is greatly appreciated
