My '84 244GL, itself a junkyard find, has its windshield replaced with glass from a junkyard. ($40 taken out by them) I bought the trim clips from Rusty at RPR ($17)and 3M brand Windowweld Urethane glue for setting the replacement glass. (You need the high-volume fast setting kind, not the flowable stuff, which is for re-sealing leaks)

The piano wire used for slicing out the old glass I got from my kid's piano teacher.

Because I was scared (by all those here on the board who have never done windshield replacement and always like to spend your money for you by insisting you must get the "pros to do it"), I installed the old-style buytl-rubber caulk (rope) as a "dam" behind the urethane to be sure I got a water-tight seal). And the only reason I did that was because the glue is applied from a caulk gun and I wasn't confident I'd lay on a consistant, uniformly thick (enough) bead. (You may need two tubes for this job, BTW)

Believe me, this job is a lot easier than others -- like changing front struts or rear trailing arm bushings.

If you decide to get glass from the junkyard, keep in mind most will be severely pitted from years of road dust hitting them. Just find the best one you can. Look for Volvo branded or Pilkington

Mask off the dash and cover the interior so you don't get glue over somethng. It is like chewing gum-stickey, only to an extreme.

This is a one-day job once you have the replacement glass. Needs 24 hours to cure, windows open, so you don't "pop" the new glass out when you close the doors.

Hardest part was cleaning up the old buytl-rubber. Pull and scrape off the most of it, then use WD-40 for the residue.

Repair any rust. Look into any possible need for a special primer with that urethane sealant, whether or not you need paint repairs. I thought I read somewhere a primer is needed to give it something to hold onto. I didn't use anything like that, just some wax/grease remover. No problems in two years.
