Crossmember attachment

[unclethumbtack]

I am doing a hp 44 and 9 inch out of 78 ford truck. I am going to use the t-n-t frame stiffener's and was searching on here for how some of the custom transmission cross members are attached. What is bugging me is how do you attach the crossmember using bolts. I am wanting to attach it like this http://i55.photobucket.com/albums/g155/zac_squatch/crossmember.jpg somebody help me out.

Cut through the floorboard, lay in a strip of 3/16" steel, 12 or so inches long in the 'frame' channel. Drill through, add nuts and washers.

Or, you can do something similar to Claytons LA kit, where the brackets weld to the 'frame' and the X member unbolts from the welded on brackets.

did some looking around for pics, coundnt find what i was looking for.... but ive seen holes cut into the unibody rail, then you weld a nut onto the top of the t&t stiffener... leaving the under side flush
