This is my $8.00 solution to the rear mast cradle. I was rear ended in my 4Runner, and salvaged the trailer hitch receiver. The body shop insisted on replacing the receiver for liability reasons. Check with body shops and see if you can get one similar.
Size: 3 items
Step 1: Get rear ended in a 2004 4Runner. Use U-bolts to attach receiver to cross member.
Step 2: Find spare mast stand and drill appropriately for the receiver pin.
Step 3: Use the safety chain eyes for a tie down point.
