tubular a arm spacers?

Hello
I am changing my mmll front cross member and want to reuse my tubular a arms, but the spacers are welded to the old cross member. The old ones are thicker then any tubing that I have ever seen and I am wondering about how thick of dom tubing using gussets I can use if I can't find any that thick at my local metal supply? I have searched on line and all I see is a arm kits, but no parts. Has anyone else had to do this, and if so what did you use?
Thanks

Good idea, thanks. Yes it is the spacers for the wider tubular lower control arms that eleminate the need for strut rods

You should be able to find what you're looking for here, http://www.welderseries.com/

I've used them for various pieces and have been very satisfied. With the $$$ exchange rate, everything on their site is cheaper in US dollars and their shipping is fast. Talk to D.W.
