Thanks guys for all the replies!
I haven't seen any shells up close or for sale to compare. As for weight, no idea what that how much the weigh but I was thinking the aluminum ones would be on the lighter end. Also since my truck didn't have the "camper" option I didn't know if that played a part in anything.
Great information, again thank you!
Edit:
My cousin that lives near the seller will be taking a look at it for me and trying to get a better price too. He'll be able to FaceTime me once he inspects it and perhaps get a lower price. Hopefully he wants to get rid of it by now, it has been listed over two weeks (but that also could mean he is staying firm on the price too). Then as luck has it, my brother is coming down to my area this weekend with a empty trailer to pick up a 1929 coupe from a customer - so I'll could be scoring free delivery from East Texas
