Back up light switch part #?

[kyotey1693]

Does anyone have the part number for the back up light switch? My truck is an 89 350/5speed. I ordered one from Vatozone but it is way too short. Did they send the wrong one or did GM install more than 1 style?

Just in case anyone runs into this issue. The 5 speeds take a 58mm switch. O'reileys and Vatozone dont stock them and cant order them. I found one at Napa and a few places online.
