Very easy to navigate and great price.

Took a little bit to get shipped but other than that good experience.

Order clutch set for 1966 corvair it is not the correct part called customer service they say don't show one yet web says the one shown is correct

NOT A 2-day shipping like I paid for, but still received the product I ordered

I wish the products had a more detailed description such as listing of it was for the right or left side or the back or front of the vehicle. Having to google part numbers to determine which area of the car was for was quite inconvenient. Other than that it was a great experience with great prices!

Easy to order! Shipped promptly and was kept imformed on expected arrival date. No muss no fuss just good service! Thanks. Pete

Good pricing and easy site to navigate
