Re: Sn-95 T-5 swap behind 3.8 Cougar/Bird How To. Reply #75 – May 22, 2019, 12:38:01 PM Thanks Jeremy. I just wanted to confirm that the imbalance of the 3.8 didn't change when coupled to different transmissions. And you are also saying that the T5 is longer than my C5, so I'll need a shorter driveshaft? Is there a driveshaft that's a direct fit, or will I have to have mine cut down? It seems like an XR7 driveshaft from a 5sp would work, but I doubt I'll have any luck finding one of those. Thanks again.
