I have a "Lights of America" Florescent fixture (4 ft - 2 bulb shop
light).

Only one bulb would light. New bulbs did not fix it. Only one side of
the fixture worked. (Always the same side).

I finally tore it apart.

I have repaired and replaced ballasts in a lot of fixtures, but this one
is unique.

I wouldn't bother it because if a fire results afterward, then the insurance might not pay. I'd call a lighting retailer to send someone out to fix or replace it.
