[sson20s]

my 69 swb is almost ready for paint and i need a tailgate ,the one i got is a good 1 for a beater ,it bowed out and my buddy who is painting my truck told me today i need a new 1,so what do you guys think an aftermarket tailgate or a really nice used 1,problem is with the used 1 is that i have not been able to find 1 ,and i have looking for about month and a half.i am just a alittle hesistant on the repop aftermarket have not heard a lot of positive things about them ,so all the info and others personal experience with them would be great to here. i gotta get 1 here in the next couple of days so they can prime and get it ready for paint ,thanks all help appreciated
