Best price for item I could find

...

it was quick and easy to order the part

good

fast

The only problem/concern I had with this product was the bolts that were included. the carriage bolts were very soft and bent. I replace them with harder bolts. Otherwise the product seems very good.

clear product description. Fast transaction

One of the top 10 places online to find the best deals on performance parts, either for street or strip. In the last two weeks I found more better deals at Autoplicity then at any other online performance parts store.. Gone_10_in_Sec..

Wanted to pay with PayPal but could not get the link to work... Also asked to combine 2 orders in to 1 and was told it was not possible...

I had never heard of Autoplicity before placing this order. I found Autoplicity via Google and decided I'd give them a try as they were the cheapest option. <br>Autoplicity did have the lowest price. The order was shipped promptly and got to me 2 days after ordering and the next day after it was shipped. I am very happy with this purchasing experience and would purchase from Autoplicity again without any hesistation.<br>
