Kirkey style seat install???

Hello everyone. I searched in the "Interior" section without much success so I thought I'd try here - since it is more of a "race" type item. I recently installed my subframe connectors and went with a ladder bar and coilovers setup and since the interior was out for welding, (as it came with a bench seat) I ordered a set of Kirkey style seats to replace the bench. I plan on getting the Kirkey brand mounts but I need a little help figuring out the best way to mount them. I'm not the best on welding/fab but I do ok as long as it's no too elaborate. If anyone has done this, your input or ideas would be appreciated.
