Looking real good.
I recently did some similar things on my interior but on the cheap (just using my nasty oem stuff)

I didnt want to post IMG's because that is too much of a thread jack :P
I just used Boommat spray on sound deadner and Duplicolor Bedliner over it on the trunk and rear seat area (to give it a smoother finish)2 Cans of each
I dyed the carpet and headliner black with Duplicolor Fabric and Vinyl after shampooing the s*** out of them. Using the shampoo brush to brush off the paint and make the carpet soft again. I used 2.5 cans for the carpet and 1.5 cans for the headliner.Everything has held up great and I drive my car almost every day. You need to be careful with the bedliner and not just drop heavy stuff on it or it will nick. Also you need floor mats or the carpet paint will start to rub off, but I have had it since April with no mats and its held up quite well.
Yes, I need a battery box. But this way works well except it wont pass track inspection. Also planning to get a pair of Low Max replica seats to finish the look.
