Al,

This is a VERY common occurence with the 126 SECs.

It can be fixed as a moderate DIY project. The instructions, very detailed, to do this reside on the Net at:

Basically it entails removing the headliner, separating the fabric from the underlying material, regluing it and then replacing the headliner.

The cost of a new headliner is somewhat prohibitive -- last time I checked it was over $1,200 just for the part. I'd expect labor to run several hours, minimum, so you'd probably be looking somewhere north of $1,500 to have the job done.

Cheers,
Gerry
