That 5th digit can't be an "0"
I think aspens started with N, volares started with an H
I could have that reversed. Haven't looked at the vin on mine lately.
Looks like you bought a 78 Aspen.
5th digit is a letter that designates original engine size.
Sure it isn't a "c" which would mean a slant 6
Or a "G" which meant it originally had a 318
