Both the 88 and my 89 had the driver's door check strap broken, which may be
a factor, but the 88 didn't have a hinge problem.

Then it also it could be the welder at the plant didn't do a very good job
either . . .

My son and I are pulling the door Thursday and then welding everywhere we
can reach with my genuine $90 Harbor Freight fluxcore wire welder

To keep the sparks in check I'm duct taping sheet metal to the "A" pillar
and door opening to deflect them away from flammables ... but we'll have the
garden hose handy just in case.
