stainless works has them on there website in ss. If you email them they can make them for you in mild steel. It will be cheaper then the ss ones, but will take them a little longer to make.

Send them an email and they will take care of you.

Ps. It also says this in the Truck manifold sticky @ the top of the FI Section.

What else would I need to get to start fabbing up my own set up?
You will need two outlet flanges for your crossover pipe. These are available from our Sponsor, Stainless Works.

You guys are talking about 2 totally different things. He is asking for flanges for the truck manifolds.

The other guys are talking about header flanges for the ls series heads from gm.

That's what I though too. Modularturbo has mild steel flanges that fit the truck manifold out lets.

If you are looking for the flanges to make headers IE: bolt to the head then they are the 12480130 flanges. These are the ones I was talking about. 3/8" mild steel $25.76 list price from GM. I don't know of the flanges that mount to the truck manifold. I do own a CNC plasma cutter and could probably knock out a few sets from 1/4" steel probably for $10/pair. I belive that stainless works has SS ones as well.

[QUOTE=BlackSuperchargedLS1;10477957]These Flanges


yes, exactly. The ones you are showing are laser cut. My machine is a plasma cutter so the edges will be a little rougher. This is the style I was saying would be $10/pair. Thanks for the picture clarification. G
