If you're not sure what to do you're better off buying a set of sfc's and putting them in.

Re: Subframe connector question
Pretty simple really, to save me some headache na a few $ I mocked mine up first. I started by using 2x4's that i ran through the table saw to get to the correct size square tubing I was using 1.5 x 2 in my case. Mine do not follow the floor, but actually intersect it, so no real bends. I them made my end peices to wrap around the front LCA mounting point. Took a few measurements and made my pieces to tie into the front frame rails.

a whole lot quicker and easier to pop for $200 or so and get a set of the Alston sfc's from Lon at Top Down Solutions - they fit, they go on easily, and require only a very minor fuel/brake line bracket bend to clear everything. powdercoated.

I have a set that I believe someone fabbed, I'll look for them tomorrow and get pictures and measurements (unless they are buried under 2 feet of snow). I think a local guy made them but I could be wrong.
