Well at the moment I'd have to say yes, there is wood in the cowl as the door posts were wood. After I get it home I'll have a better idea. Doesn't your 37 have all steel supports? If so couldn't you swap that into your 36? I'm planning on using all steel in mine as it will see daily use as a work truck. After it's finished I plan on hauling one of my ex's cars out to New Mexico with it. Unfortunately, I like you have limited inside work space. In fact the 36 will not even fit inside my shop.
