WTB Hatch sliding doors

Looking for a set of these for my dad's boat, V20 late 80's early 90's if I remember right. Only really need the rear one, but willing to buy the full pair if need be.

If anyone knows where they could be purchased new, would like to hear, have not been able to find anything searching around on the web.

Also need the small hatch door over the batteries.

thx...Angelo
