Is there a "Master Kit" out there for window felts, weatherstrip, window rubbers?

Dont take this the wrong way. Are you a mfg ot supplier? Both?
I see no reason that a MFG or supplier cant do a "kit".
Not everyone buys 1 tire...some 2, some 3. Quite often buy 3, get one free.
I'm working on our 67 cuda. Needs a vent window seal. Well while I'm at it I may as well do the window felts and door rubbers. Heck know what , im gonna do both doors.
See, tere's logic to it. It's all for the same vehicle, not like 4 different vehicles with parts from bumper to gas cap.
It takes organizing on mfg or suppliers part, that's all.
Seems logical to me.
