Planning on doing the same thing this summer. Sure it's easier to sell the NA and buy a TT but there is no way I could add a back seat to a TT so I'm going to have to go the way of the TT swap on my 2+2. I have obtained most of my info on swapping from just checking the tech forum periodically and doing searches. Actually better than reading my shop manual. To all members: Keep up the banter. This really helps. BTW, I have really enjoyed your posts, ConVerTT!!
