No the difference in minimal. How are the felts that glass runs up and down in?. That stuff can be bought no problem. Does the back window slide up and down or stationary? The windshield goes into the frame with a cork packing. Could use other things now been out of it too long. I'd leave that to the glass shop to put it in the frame. Everything else you can do. I wish you lived closer I'd love to help you.
