Would you do this?

Two things:

Price: If the price was about the same (maybe even I little bit more), I always go with the local speed shop.

Customer Service: If the local speed shop takes care of me or at least makes me feel like thy are, they will get my business. If not, I'll go to mail-order parts houses. Luckily, We still have two operating in the area that have been in business for approx. 45-50 years/ea and are very good about how they treat their customers.
