autozone carries pennzoil syncromesh in some places. It does not state gl4 but is known to be the same as other syncromesh.
I used sta-lube from napa. It is a heavier weight but it is much cheaper then anything out there, over the counter and gl4. Worked great most of the year. During really cold mornings it was really thick until the car warmed up.
