FYI: I sent a message to GODMAN PERFORMANCE since their great website said they had such a product. I requested the price and availability for an aluminum brake booster check valve.
After getting no response after a few days, I sent another message inquiring why they hadn't responded.
Today I received a very sarcastic response from the company that said they don't have any techs just sitting around to answer e-mails and to call them if I want to ask a technical question. Again, this was a request for price and availability. I don't consider that to be very technical, but maybe they do.
I sent the company the appropriate response to their lack of customer service. I also contacted SUMMIT RACING and they came through with exactly what I wanted and at NO COST!
SUMMIT RACING is a company with good customer service policies. The other company deserves to lose customers.
