So I am in the market for a driveshaft. I am going chromoly shaft with chromoly trans and pinion yokes. Just not sure if I should get a 3in or 3.5 in shaft and who to buy from. I have checked with PST, Dynotech, Dennys and Strange. Dennys is the most expensive on both sizes. Looks like Strange is the cheapest on a 3in and PST and Dynotech on a 3.5. Anybody have a input on who they used and any real advantage on 3.5 over 3in?
