Tomorrow I'll have to investigate if there is a door behind our patch or if it was simply removed. Does anyone have information on what heater unit was in there and/or access to plans on how to build a stock looking cover like seen here?
That door could have been for the battery, since a spare tire was installed on the front, where the battery was originally located.
The photo is for a 62 or 63.
