Fantastic service and communication

A specific nut that I needed on the restoration of my 71 Plymouth Roadrunner is no longer available or manufactured so I spent a lot of time getting feedback from parts distributors as to where to find anything close to what I needed. I was referred to FMW fasteners and searched their site and found a part very close to the original nut that I needed to fasten the hood bezels that have the engine call out numbers on them. They take a specific nut/washer combination. I spoke with the representative at FMW and even sent pics of the original hardware to match and after discussing several options was sent 2 different sizes to try and one of them works perfectly and although appearance isn’t 100% exact, it is very close and acceptable! Fantastic communication and excellent service! The nut also has an original Chrysler item number identification so was used by Chrysler. Thanks for your excellent advice and communication as well as quick shipping!
