Mine are the ones made by Kilmartin. https://www.kas-kilmartin.com.au/Austin Healey.htm.
I can see why you are frustrated. I couldn't find the vents when I went to the site for a link.John, is there a way to search the Kilmartin web site for the part we want without scrolling thru every piece they make? Or am I just missing it. I could build a whole AH frame before I find a single part I need on that web site.
Thanks. Pardon my venting, that site has frustrated me before.
Contact British Car Specialists in Stockton, CA. They carry their parts.Yea, it’s hard to navigate through their site. I also contacted them a few months ago to order some parts and never received a response.
