Does anyone know where i can buy an after market seat for a 1990 GMC Sierra Regular cab? ?

Question

any seat.

I'm looking for one with a head rest.

Brand new not used.

Answer 1

Check out jcwhitney.com or just type in truck accessories in yahoo search.  If you want to keep the factory look I would search the local junkyards instead of paying for aftermarket.  You can buy the seats out of a wrecked GMC from 1990-2000 model truck and should have no problem with install.

Answer 2

i would suggest going to
