Whirlpool super capacity dryer

Looking a supplier of whirlpool part number 4392065 which is a kit containing belt , idler pulley assembly and drum rollers . the idle pulley assembly fitted to machine is a friction type without a wheel , think they wear the belts out quicker , which is why it was discontinued , looking it as quick as possible as dryer belongs to the local football team and they need there kits drying . full model number of machine is , Whirlpool 3XLER5435HQ0 , even belt which is part number 341241 and pulley assembly part number wp691366 would do ok. But the sooner I can get them the better , thanks in advance Darren
