Casey: This might take some research. I know that all the Body Shops in this area have completly quit installing glass.
They found that the cost, vs breakage and loss, made it more practical and economic to leave the Glass work to Glass installers.
There are specialty installers that come out in a van and will install in a parking lot for less than they can and guaranee their work.
You very well may well find that it is cheaper to have a pro do the job. They can usually do in less than an hour what the less experienced would take all day to do.
No doubt Lexan would work, but cutting to fit and install may be pretty difficult to do and it is pricey stuff to mess up the job.
It has to be just right to fit and not leak when done. If that has no break in the gasket then the glass/lexan has to be fit to the gasket and then a Handle with a hook on it is used to roll the gasket into the frame. The hook looed like a utility knife handle with a very stiff #9 wire U shapped hook.
It's not really that bad if you have done a few hundred, but it takes a knack and learning the technique or you will discover that you vocabulary is much more developed (or is that underdeveloped?) than you knew.
I installed Lexan windows in Grinder Mixer tanks at the factory for a short time, but learned quickly that there were others much better at it than I.. BTW that's a nice Topper and would be well worth repairing.
