Needed something to pull myself up into the van. Saw the tapped hole in the passenger side rear door frame at the right location about 40" above the van floor. It is a 10 mm tapped hole. Used a 10mm x 120mm long bolt. Made a 3/4" long wood dowel spacer by drilling a 13/32" hole through the wood dowel. Put a flat washer between the bolt head and the dowel. Tightened the bolt and then shortened a bicycle handle bar rubber grip to put on the dowel.
