Moparguy, are you saying you have a T-5 behind a 216?
Carl,that's right. The truck is a documented 45,000 mile unit (I'm responsible for about 4k of those). The only two upgrades I've made are new 16" wheels with modern 215/85/16 tires and the T5 with a one piece drive shaft. Of course there's been tons of work to make it a safe stoppable daily driver.
I'd be hard pressed to say which upgrade was best, but both have made it a joy to drive. And yelp, even with the 4.57s I have to use all 82 hp occasionally.
