Here's a good resource for looking up parts at junkyards:

www.car-part.com

There's a listing of salvage yards by city/state here
croll down to view all yards located in MA.
I don't think they list dipsticks in the parts look up on that site, so your best bet is to just call the ones closest to you and ask.
