Needed parts for 78 GMC

[iufan71]

Was wondering if anyone out there might have a few parts im in need of for my 78 GMC truck......(1) 77-80 arm rest....tan would be nice,but any color would do, driver side outer weatherstripping for where window goes down into door. And i took a bed from an 85 gmc,so i need the black piece that holds the gas filler neck in place behind the gas door,and the main hose and the small hose that go into the gas tank. Also,looking for a/c hoses and a bed mat. Thanks. Chris
