Yeah, my factory stock B-body A-arms weighed 10-1/2 Lbs for the pair and with using the Magnum tubular A-arms which weighed 8-1/4 Lbs a pair, I saved 2-1/4 Lbs total. I also used Titanium lower shock bolts and nuts and upper Titanium nuts and washers. Saved 1/4 lb total on those.
Sparingly working on my 6061-T6 Aluminum Transmission cross member. Will post photos when I finish some time soon. No time for fun.
