63 full frame build help!!!!

[lowlife4life]

Well I'm new to the posting but have been lurking for months. I just bought a 63 chev and a 61 GMC. The 63 is being built by me fully bagged and a 6.2 cts v engine. I bought the truck already sitting on a 98 1\2 ton frame. Which will not let it lay rockers without sectioning the bottom of frame so the plan is a 2 x4 full frame looking for some ideas for a front cross member the truck is being built on a somewhat budget any help would be greatly appreciated
