If you decide to use the old windshield and should you want to replace the glass at a later date as and when funds allow....it's possible to remove the old glass without wrecking the rubber.
I assume you are planning on fitting your old glass with a new rubber meantime? To get your old windshield back out you will probably have to 'sacrifice' the glass. The way I usually do it is to sit in the seat and apply pressure with a well placed foot,starting at a top corner push the glass and at the same time 'flick' the rubber lip with a plastic glazing stick.(A blunted flat screwdriver with the end taped up would suffice)So as not to wreck your paint. It should then start to unlip.Don't push so hard that the glass pops out on to your hood! Apply steady and even pressure as you go and it should slowly work itself out.
Warning...The glass may crack so wear goggles and sheet up your hood to protect your paint etc.Also tape over your demister vents.
Builders right though. Try and fit a new glass you'll be amazed at the difference!
Good luck! Jock.
Wear stout gloves too!!
