all the paper work for my truck says "1990"
but the owners manual says 1989 also check this picture out..
so im pretty lost also this is my first car well truck but you know what i mean.
if u can help me out thanks.

 

built in 89 for the "new" year of 90. my 80 was built in 10/79.

 

ok cool thanks

 

but unless someone corrects me i believe these trucks (89-90) are the same as far as parts (like when you would go into auto zone)

 

yep 89 and 90 are the same no difference

 

I believe you can even go up one more year 89 to 91, if you looking to replace body parts such as front end , and things like that.
