Car # 1 in the 80's

Today I saw an old sticker on a truck that featured car #1. I don't know if it's BGN or Winston cup but I'm pretty sure it's out of the 1980's.
I have been racking my brain all day trying to put a name to the number. The way the sun was hitting it I couldn't even tell what color was on the dang thing!
Can anyone out there help this poor girl before she pulls her hair out?
Thanks muchly,
Krista :confused:

The car I was referring to was the Pontiac #1 of R & L Carriers in 1997, it was green and yellow. Must've been a BGN car!:)
