So far so good. No description about which brake pads were for the front and which were for the back though. I haven't had a chance to install these yet but shipping was fast.

Good so far

Just need part asap. Thanks

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
