Hello All, Im fixin to tackle replacing my evap core on my 97 Silverado 4X4 Ext Cab and am looking for help. This has been a chain reaction of things breaking after trying to replace the manifold line up top. I priced having it done and can not afford $750 right now. Im capable of doing it, I just cant find any pdf downloads, pics or anything. I know the dash and all has to come out, but I need some guidance. Thanks
