Just finished installing rear glass in my 46 GMC.getting the glass in was a three hour test of my patience but I prevailed.I used a trick I came up with years ago when I was rigging boats to install the nylon rope insert in the rub rail.Not shure if it will work on the chrome lock strip but made inserting the rubber one I am using a snap.thread the strip into a 9mm (12point) craftsman box wrench,work box end of wrench into window gasket,don,t forget lots of soapy water.As you push the wrench along the gasket the insert will fall into groove which is being opened up by the wrench.be shure to check that the lock strip is going in corectly without twisting.when you get to the end don,t cut to short and push ends in with plastic tool.P.S.wrap the open end of wrench with cloth and tape so it dosent tear your palm up.
