Is glass for 63 Safari anything special ?
The '63 Airstreams used a very similar Hehr window style when compared to the '64s. The glass is flat, and can be readily replaced with flat (tempered probably would be best) stock. The greatest problem may be with the gasket material - - the last window replacement in my '64 Overlander required reuse of the original gaskets as the dealer couldn't locate appropriate replacement gaskets - - a silicone product was used to supplement the old gasket when it was reinstalled - - Inland RV may have the appropriate gasket material by now (my last experience with a broken window was in 1996). If the jalousied window (I don't know if the Safaris had them) - - next to the entrance door was involved, care needs to be exercised with the metal glass retainers as these are becoming more difficult to find.
