I made my spare tire holder today. Its a copy of one I made for my cube van-which has been working fine for years.
I measured out the space behind the fuel tank-there was plenty of room. There was one small crossmember-I welded in another so the tire would have something to rest on.
The winch to raise + lower the tire was a ebay $15 special.
I made a plate to mount the winch on+ welded it to the frame.
I welded a piece of 1"sq tubing between the crossmembers + welded a pulley to it.
Things were set up so the cable would fall right in the middle of the open area.
This piece is what picks up the wheel.
It helps if you prop the tire up on a piece of wood 1st-but you feed the holder thru the hole + line up the pins in the lug holes.
I throw a safety chain around the wheel-and also have a rachet stap on there just in case.
