yeah the cord trick is supposed to be great but i have never tried it i just use a box knife with brand new blade and works great if you dont need to save weatehrstripping and are buying new at the store too, they are around 30 bucks new which is worth it if you care about the truck much
anyone installing or removing a windshield is gambling, no matter if new or used or whatever. just be careful take your time, i can remove even a van fullsize windshield all by myself easily i have great luck with them i have never accidently bropken any windshield except one i dropped inside building cuz it ran into parts when i was carrying it, it was a factory tint 67-72 truck windshield, oops and was the last 67-72 glass i had /forums/images/graemlins/frown.gif
but ive taken a tons of them out, cars trucks vans everything, soo..
if there was enoguh population and any older trucks and stuff around here and a demand to have glass replaced then id seriously consider starting a glass replacing service, but where i live is dead and no one restores anything and i dont hear much about anyone ever needing glass replaced on older stuff, so.,,. but i would relocate and go in with someone else on starting such a service, if possible, if i had the right attachment for reciprocating saw motor then i could do the later non-weatherstripping type glass replacemment too, but i dont have that right now, or even a reciprocating saw motor either, i have access to some though,. you have to center those windshield with clips after cleaning off bed of glue and applying new and sometimes using brush on primer first. and have to remove interior windshield opening trim moldings too, the attachment works form inside of vehicle all way around windshield, real easy
hum..
good luck
