good place to buy parts online

Yup a Discount Auto Parts store near moms house has been there long as I can remember. Never got a wrong or bad part from them.
Back in the 80s when I first attempted late A disc brake conversion on 67 cuda, the lady there cross referenced all the suspension parts in books to help me figure out what was needed. I can remember her saying, "I would want a car that had belonged to you. I wouldn't know which parts to buy for it." Seems comical today.
I'll pick up little stuff like clamps and fluids from Awfulzone but my hard parts come from Discount or Carquest Auto Parts stores.
