I am picking it up next weekend and it was too dark in the barn to get any other good pictures, but once shes home I will take plenty!
And once its home I can delve deeper into finding out what kind of conversion it was. That is good to know that b300 will work for some of its parts.
I think most of the body is fiberglass mounted onto a steel frame. 30+ year old fiberglass is going to need some work on it as I noticed a few cracks and crazing. I have built fiberglass speaker boxes in the past so I am not too intimidated by this task but any insight or recommendations would helpful. I am thinking of ordering the supplies now so I can get this sealed up and waterproofed ASAP as I dont have the luxury of keeping it in a barn!
