Apparently with 2.77's, 3.27's. and 3.45's. Anyone know what speedo gears I'd need for a T-5 (with 3.27's or 3.45's) and/or what the length of the rear end is? Also, were the 9-bolts all limited slip?

I don't think you can the exact speedo gears for the 9 bolt ratios anymore. I just recently swapped in a 2.77 9 bolt and wound up using the gears for the 2.73 ratio. This shouldn't make any real difference,maybe a 1/2-1 mph difference between the two. The dealers however still have all the gears for the 10 bolt ratios so you should be able to get them. Just tell the dealer what ratio you have and they should be able to hook you up.

Yep, like Mongoose (Mike) said. Although I can't input for your 5 speed, the gears for the 2.73/2.77, 3.23/3.27, and 3.42/3.45 (10/9 bolt ratios) with autos are all the same for 9 and 10 bolts. The 2-5 hundredths make no difference in MPH in these applications, so it would stand to reason that the 5 speed gears would interchange in the same manner.
