Not really sure as the 3" wide backbone on the frame sucks................I have a 83 maxim and am looking. Its actually whats keeping me from going forward as I haven't found anything that will work without major modification. I would think any tank with a deep tunnel would be a good choice though.
I have modified a 80s 400 tank but didn't like the looks. Have a XS 750 tank now but not sure its going to fly either.
If you do find anything post up some pics.
