Cant find SID for a fund

I am trying to backtest data going into 2002, as many ETFs started only after 2009, I simulate the trades using funds. I try to trade the following fund : Vanguard Long-Term Treasury Inv (VUSTX)
However, Quantopian cant find the symbol nor the SID for this. Any idea how can I trade it ? same for symbol VUSTX and others.

Symbol names that end with X are for mutual funds, not ETFs. Quantopian database does not have mutual funds.

Thanks for that. If funds does not exist, did anyone used fetcher for that and/or for stocks backtesting starting from the 90's ? For many algos going back to 2002 is not enough to check all market situations, it would be nice to have plug-n-play code with data before hand and/or funds.
