Bend Transmission & Motor

I have a wedge shaped piece on my layout and was trying to figure out what to do with it. I combed through some photos and was unable to find exactly what was in that area in the 60's so I decided to do a little freelancing. I wanted to have some sort of auto repair or shop and decided to model a transmission and motor rebuilding shop. This way I can have both small and large vehicles being worked on in the same place. This will also give me a reason to buy more vehicles....
