I have the part number but keep in mind these are from GM Parts Direct. You can almost definitely get them for cheaper somewhere else.
HUD = 9364292 = $558 shipped
Graphite Dash Panel = 10403050 = $44 shipped
HUD Switch = 10402058 = $30 shipped
Hope this helps.
BTW, if you can find a junk yard you can probally get the whole unit for under $50.
