For funds I would use the benchmark to back test as long as it seems reasonable but some funds probably benchmark off each other and are bad regardless. Every company is different so stocks are kind of iffy to substitute.
Also depending on who holds your fund, it could be an easy substitute. For instance, Vanguard has a S&P 500 ETF (newest), S&P 500 Admiral Shares (middle), and S&P 500 (oldest) which all generally return the same amount and the fees are similar as well within a couple basis points.
