aftermarket minitubbed

Has anybody mini tubbed their car using a full steel wheel tub such as competition engineering or s&w racecars wheel tubs? I'm mini tubbing my dart right now and I've decided on using an aftermarket tub, but I'm not too sure on which size to buy. I've measured a dozen times and even made a cardboard template and it seems to me that a 36" tub will work and still allow me to retain my factory trunk hinges. I may have to cut off the tension rod supports and use a prop rod to hold the trunk up though. I was curious if anybody else has taken this approach to mini tubbing their car and would like to know the size of the tub they used and maybe some pics.
