When I look at their website, all I see is ones for 429/460.

 

Welds still holding.

 

Yeah, they dropped them from the website within the last year. I wanted to order a set and weld them myself, but I didn't have the cash and when I did, they were gone.
I was thinking about emailing them to see if they will still make them despite not being on the website, but my wife got a project truck too and poof, the cash was gone! Some day... lol.
