Roy,
i just finished the Quad w/ limber & 25 pounder last month.
there is no rack for the spare in that kit!
the spare tire has pins on it, and you can drill out / cut out
holes in the rear deck. the tire mounts flush.
there was a thread w/ rack for spare, as some guys were scratchbuilding them.
hey! that was a reply to your old post!
