The starter of the 1994 GMC Sierra 1500 pickup is located on the dashboard. It is usually attached by a small wire.

My 1992 had 6" Factory Round speakers in the front doors and 6 X 8 Factory speakers in the back. My 1998 has Factory 6X 8 speakers in the back (extended cab) and haven't checked the front ones yet. my 1994 has 6"x8" as well in the front and rear.

It will be slightly oversized 6.5" speakers if the car came without a factory CD Player, or 6" x 9"s with factory CD player.
Yes there are some, and replacements were still available on Ebay last I checked
