Glad to hear from you again. I'll vouch for you, the quality of the items you made in the past were identical to the original. I might add, Mike's parts come ready to paint, you don't have to drill any holes, etc. Hope you are still making the ECO parts the way you did years ago.
Take a look at Mike's profile, he has been around OG since 2001.
