Hi Toma

BTDT. Your  looing for a "spring Pin", do not get a "roll pin", very
similar but the spring pin is the replacment.

Next issue, the spring pin on the van is a metric, whereas the Auto
parts ones will likely be English.  Do not dispair as this is good.  The
arm rest holes get a bit elongated and so the arm rest wiggles a little
or a lot depending on how bad the elongation.

Any, by drilling out the holes to match the new sized spring pin you'll
fix the sloppy problem too.

Other tips,  have the end of the roll pin chamfered to aid in the
reinstallation processs.  Also measure the needed length.  My part house
was either our or didn't have the correct length and had to cut a long
one down.

Sincerely,
Mark Keller
