Thanks for the replies.
The floor is concrete so no digging option and the interior is the same height as the header so no expansion other than raising the whole roof which on a 36x36 barn would be way too expensive. (If I would have built the barn it would have 12ft height at least).
I have the dollies for moving around classic cars that I own so moving it is not a huge issue other than getting over the 1" concrete threshold into the space. Just not sure if I will save enough height even sitting on just rims.
Another idea. Can I take off the wheels and set it down on the brake drums in the dollies? After I get it in I might be able to raise it up a bit and put jack stands under the axles. Not sure if it would hurt the brake drums.
Final idea of course is just plan on leaving it outside covered but I tend to exhaust all the mod ideas before going with the obvious solution
