Guys - thank you very much for replying.

ok. so it called bulkhead cover.
but Im trying to look for it "bulkhead cover" in Ebay - and i cant trace this part.
even when i search for the part number, i cant trace it .

actually the all plastic parts, all around the bulkhead cover are also in a bad condition.
I dont mind to buy a set of parts( should be around 6 -8 parts including the bulkhead cover right?) that takes care everthing on this area.

can someone here provide a link in ebay or some place else to theis part?
also can some here place a link to a part set of this area ?

thx
