Yes, they're sold through v8roadsters.com. 1-3/4" primaries.

Star, beautiful fabrication work. I wish I had a TIG at home so I could attempt to make my welds look half that good. I can lay beads like that on a bench with freshly sandblasted material, but I couldn't imagine doing that in an engine bay on this sheet metal.

wow, nice work guys. I'm curious about those billet knuckles?

Gotcha. I didn't realize that was who manufactured them for V8R.

Sorry guys.. when I get busy in the shop I can't find the time to get back on here to post more pics... here's a few more from the beginning of last year

Had to fabricate a "much" needed support for the tubular subframe
Notice the rear lower control arm mounts that have high stress in turns and under braking

Also nice to have added protection for the headers

Some more chassis stiffening before we start seam welding the rest of the chassis<a href="http://s840.photobucket.com/user/eliminator77/media/Mobile%20Uploads/2016-04/933C4A09-97E4-4D7D-AF3B-50B6A2E021B5_zpsohrio3ci.jpg.html" target="_blank"><img src="http://i840.photobucket.com/albums/zz325/eliminator77/Mobile%20Uploads/2016-04/933C4A09-97E4-4D7D-AF3B-50B6A2E021B5_zpsohrio3ci.jpg" border="0" alt=" photo 933C4A09-97E4-4D7D-AF3B-50B6A2E021B5_zpsohrio3ci.jpg"></a>

It is a privilege to be looking at those neat and tidy welds.
