You can try a heat gun to soften it, a putty knife to scrape it, but there's a risk of gouging the glass

You can access the torque box bolts from the top by removing the sill plate and rubber mat and drilling a few 1.5-2.0" holes in the fiberglass. Use Kroil or PB Blaster on them from the top.

I was trying to give him some idea of the way the latch worked. He sent me pics that clearly show the pivot spring, although they looked so rusty, one would think they would have broken with any exertion..

I was looking at some of the many photos I have and must remark that up to early 89 (0420's) the latches were very similar to 63 and up, however on two 89's numbering in the 0458 and 0459, there's only ONE latch and it's right next to the wiper moor
