If you are in a warm climate, do it in the sun on a warm day. It makes the rubber more pliable. Definitely get help and don't let them get ahead of you if they are a novice too. I put the rubber on the windshiled and place a nylon string in the outside groove of the rubber. The string ends should meet in the middle of the top, and then leave the ends hang out on the inside if the wind shield. I use some masking tape to hold the rubber in place on the windshield.
On the '60 you have the cab overhang at the top of the windshield. The top of the windshield has to be put in place first. That is not as easy as the bottom first. You won't be able to tip it into place if you start at the bottom. Make sure it is centered or you may have to take it out after you get going and start over.
Use a windshield tool to get the rubber in place around the cab opening. Don't use screw drivers. That rear window is a piece of cake compared to that windshield. That windshield is "expensive" to replace as I am sure you are aware of.
If you ar trying to bang on the glass with your hand, use the whole hand like you are spanking. Don't bang on it with your fist.
Make sure you have enough time to start and finish without interuptions. Take your time. Don't rush it. If you start to get frustrated, stop and go take a break. This is no time to loose patience.
There are a ton more tips that I'm sure will get chimed in on this post.

Good luck.
P.S. You could always bring it to a glass shop and let the guys who do it every day get it in for you. It might be a good idea, on that windshield, if you have never done it before.
