The Hot Rod Company does it.

I just ordered the Hot rod Company cloth covered spark plug wired for my flathead. Took almost a week to ship, I wish everyone did that good on delivery. Good guys and fair prices AND they gave me the HAMB discount.

I've placed several orders with Mike over the years and everything is always top notch. Latest order just arrived earlier than expected and The Hot Rod Company continues to be my go-to place for all things cool!!
