Back glass quandry on my '71.

[barn9]

As some of you know, one of the panes on my rear slider was shot out a week ago by some punks. Since they also shot out 110 others, the local glass shop is booked up for a few weeks, and till he looks at my window, he is not sure if that pane can be replaced (doesn't look like it can to me). So, I am looking at rear windows. Now my dilemma, I like having the slider for ventilation, so I am leaning that direction, but the ones I have found so far are black framed (mine is aluminum, unfinished). If I do have to replace it, I think the black might look better, so not a problem, just have to decide about tint. Now, here is what I would like to ask of all of you, or specifically those that have done it:

1. I assume I should get a new gasket/seal also, and I have the custom trim, so how difficult is it to install? Or should I just have the glass shop do it and be protected against screw-ups (I'm perfectly capable of screwing something up )?

2. Since I had the truck painted several years ago, and they did not remove the back glass, am I going to run into any problems using a different gasket?

3. Does anyone have any installation horror stories, or tips that may help or keep me from screwing up (see 1. above)?

4. I would like to see some pics of black framed back sliders to help me decide between that option or going back to the original full glass if possible also.

As always, appreciate your help!
